[@yuan-jia]

People need to understand the lens doesn't become a f1.2 because you put some sort of glass in between the lens and the sensor. It just becomes a f1.8 lens "again". Because when you put a 50mm f1.8 on a MFT camera you don't get a 100mm f1.8 look, you get a 100mm f2.5 look. So putting this glass in between just gives you back the look AND the light of a 50mm f1.8.

[@pathosmovies]

guys, speed booster does not affect DoF and the aperture is not affected by crop. The Speedbooster does nothing more than capturing a picture of a bigger image circle and projects it to a smaller image circle. Like a magnifing glass bunches the sunlight in one point. Thats why "aperture" is increased.

[@kleinzype]

Is it possible to use autofocus (with a usm lens for example) with the speedbooster?

[@Zahhm]

Not sure if you're aware but crop factor affects both focal length and aperture. The speedbooster allows the MFT sensor to see the 50 1.8 as it is. It is not physically possible for the 50 1.8 to become a 50 1.2 just because of the adapter. Focal length and aperture must be balanced or else you break math.

[@VadimsVizions]

Your metabones adapter is the Nikon version. It is cheaper than the Canon one but will it give you the same f stop increase and crop factor as the Canon one?

[@mrdinjemek]

What if you use this on a full frame sensor will it make a full frame even more wider?

[@stephenericwalsh]

+TruthSeeker No. It has a smaller image circle that doesn't cover the full frame. Also, it won't fit on the camera.

[@VoyagerVideoLLC]

Hello nice vid! I think though that possibly your calculations are incorrect, but please correct me if I am looking at this the wrong way. You state the 50mm 1.8 becomes a FF equivalent of an 82mm f1.2 with the Speedbooster. However I believe in reality it becomes a FF equivalent of an 82mm f2.8 With just a regular adapter the 50mm f1.8 is equivalent to a 115mm f4 - you have to apply the crop to the aperture as well. The Speedbooster reduces the crop by .71 (and thus increases the aperture) - the marketing for the SB seems to indicate it does two separate things (widens FOV and increases aperture) when the one is actually the result of the other. So when you apply the .71 increase to the the lenses FF equivalent (115mm f4), you get 82mm f2.8 - and a MFT equivalent to this lens is a 35mm f1.2

[@MaksimYuryev]

Voyager you are so right! I'm sorry If I said it incorrectly I just meant the focal length equivalent FOV equivalent, not DOF equivalent. Thank you for clearing it up!

[@VoyagerVideoLLC]

Max Yuryev Sure thing! Also, I find it easier to deal with Super-35 equivalents instead of FF equivalents, especially when using a Speedbooster as the sensor is now roughly the same size as S-35. If you're using a S-35 camera, the standard lenses used are 24, 28, 35, 50, 85, 100, etc. So a 35mm or 50mm lens would be used for a normal angle, and these have a 50mm and 75mm FF equivalent but that's kind of irrelevant... the DSLR revolution has made things more confusing than they have to be. So ultimately, the 50mm f1.8 with the Speedbooster is about the same as using an 50mm f1.8 lens on a Super-35mm camera. Without the SB, it's like using a 75mm f2.8 on a Super-35 camera.

[@jonatanjimenez3819]

I have a doubt If you fit Speedbooster you can use lens with more light but for video it's crazy to focus with f1.8 or less. Any advice? Using external light or put iso higher but it generes grain...

[@jasonlindquistmedia]

keep it up, love all the gh4 videos you make

[@MaksimYuryev]

Thanks Jason! Come join the forum! GH4Shooter.com

[@christianpauldugenia4616]

pls pls pls pls enlighten me....so if speedbooster is used, do you lose the auto-focus capability???

[@Dezdirectz]

aian paul Yes

[@stoneofkindness1665]

The NOOK Cafe Quick shoot at a great little cafe...CineD/ -5 sharpness hand held 35-100/ 2.8/IS I also used a few stills to tell the story.

[@TheBrightPixel]

Correct me if I'm wrong, but I think you aren't quite right on the math there. When you put a lens on a MFT sensor you actually lose a whole stop of light due to the crop. For example if you put an f1.5 Cine lens on a GH4, it actually becomes an f3.0 lens. So putting the speedbooster on only regains some (not even all) of that loss. So actually you're lens only ends up slightly slower rather than 1 full stop slower - and not actually faster than the rating on the lens at all. And you still don't get quite as much DOF as the same lens on a full frame camera. No? I'm not saying that they're not good - just saying that they're not as good as the numbers everybody seems to think they are.

[@MaksimYuryev]

The Bright Pixel Well it really depends on what your thinking about. If your using the F-stop to guage DOF then yes your right, but if your using for the amount of light that is hitting the sensor (relative to sensor size) then it still works out the same way. A F2.8 M43 lens at iso 200 will expose the same as a F2.8 lens on a full frame at iso200 but of course the DOF will be different. I'm using the numbers to calculate exposure not DOF.

[@TheBrightPixel]

Max Yuryev Yep, got it. Thanks for the clarification. It's a tricky business :) And really a LOT of people are not aware of the DOF loss with the crop sensor. Many tutorials just don't even mention it (like yours for example)

[@mgoldermann]

There seems to be a common misconception with how Speeboosters affect DOF. Granted, Speedboosters add an extra stop of light to taking lenses (so to say, but not really), but the primary contributor to the increase in the shallowness of the DOF is the increase in FOV. For example, with a 50mm Nikon lens and a 50mm MFT lens, both shooting in the exact same lighting conditions, the MFT lens will have to be further away from the subject to achieve the same composition as the 50mm Nikon lens, whereas the 50mm Nikon lens is able to achieve the same composition much closer to the subject, which further separates the subject from the background.

[@MaksimYuryev]

+Michael Goldermann I totally agree, I don't go into detail how this works as it causes more confusion anytime I bring this up (with most people) easier just to say it allows a shallower DOF.

[@ganzgrosserjunge]

Hi. Thank you for this video. How about autofocus. I am using a nikkor 35mm f1.8. Is it as fast as using panasonic lens?

[@MaksimYuryev]

The metabones Nikon to M43 speedbooster does not support electronics so no autofocus.

[@PaulNelsonphotography]

Your videos are great! Thanks for sharing!

[@MaksimYuryev]

Thank you!

[@yrsherman]

do you loose light when using regular adapter not a speed booster?

[@koolkutz7]

To be honest I just use the Panasonic 25mm f1.4 on my G6 (for 1080p) which is a killer lens. Or if you want to go wider, maybe the 20mm f1.7 would be good, no adapters needed (albeit you are not gaining 1 extra stop).

[@kuntaleroy7414]

I purchased the Metabones Canon EF/ Micro 4/3 Speed Booster XL-BL from B&H Photo in April of 2016. My application was using the Panasonic GH-4 and the Speed Booster with the many Canon lenses I had accumulated. The unit worked well most of the time, but the GH-4 would occasionally show the “Lens attachment failed” error screen when I attached a different lens. I thought it was the lens choice, but noticed that all but one of the lenses I had were original Canon units. On 09/29/2016 the GH-4 firmware was updated to version V25 and the Speed Booster interface problem began to occur much more frequently. I continued to think it may have been due to my inexperience with the GH-4 camera functions, so I tried to learn about and attempt almost every combination of camera and lens settings. Nothing worked. On 12/07/2016 the Speed Booster firmware was updated to version V2.5, and on 12/08/2016 the GH-4 firmware was again updated to version V26. Now EVERY lens I try to attach gives the same attachment failure error message. I can only use the combination if I place the lens inside the Speed Booster mount but only turn enough to secure it without actually connecting the contacts of the lens and the Speed Booster. Of course this won’t allow any lens communication with the camera, but will still allow the use of the lens as a completely manual unit. I have tried both the Green Power-Save mode (default) and the Advanced Manual Focus mode on the Speed Booster and I still get the same results. I find it almost unbearable that I purchased this unit mainly for the ability to use my Canon lenses on the GH-4 like I use them on my Canon bodies, i.e. with full control of the lens focus functions. I can’t believe a $650 unit designed to do this, heralded as the best unit of its type available in the marketplace, only lasted for a few months before failing completely. Of course I am beyond the 30 day period usually given for a return window. I could never give this unit more than one star, and would seriously love to give it much less than one star, if that were possible. I have never been as disappointed with a seemingly serious photography product as I have been with this Metabones unit.

[@MaksimYuryev]

Have you tried the GH4 option shoot without lens so it wouldn't give you that message?

[@kuntaleroy7414]

Yes, of course. The shoot without lens option on my GH-4 does not remove the problem. I have read about this very issue in other KZbin reviews of this adapter.

[@kuntaleroy7414]

UPDATE: I obtained the information I needed to possibly get the unit repaired on 12/27/2016 and sent the Speed Booster to Hong Kong for repair (as is required by Metabones). I was required to pay the cost to ship there and back, along with any other custom fees for international shipping. I had no claim number and no guarantee that the repair will be accepted as a warranty covered item. I received the “repaired” Metabones Speed Booster back from Hong Kong on Monday (01/16/2017) along with the return documents. The unit was unpacked, removed from the plastic storage container, and immediately mounted on my Panasonic GH4 camera body. I then attempted to mount three Canon lenses in succession on the adapter- (EF 17-40mm f/4L, EF 24-105mm f/4L, and EF 70-200mm f/2.8L). Each lens I mounted failed any identification and acceptance by the GH4 camera. In other words, the Metabones unit was acting the same as before the repair process. I then decided to eliminate any possibility that my camera body was at fault by arranging a test protocol with a local camera dealer here in town. I took the Metabones Speed Booster, along with my camera bodies and lenses, to the camera shop for bench testing. When I arrived and discussed the issue with the store owner, he suggested I first attempt to mount the Speed Booster on two new camera bodies and witness the results before any bench testing was done. We mounted the Metabones unit on a new Olympus E-M1 Mark II camera body, attached an EF lens, and turned the camera on. The Olympus camera failed to accept or even recognize the lens and would not allow light to pass through the Speed Booster, and into the camera. We then tried two other Canon lenses, only to get the same results. Next we unboxed a brand new Panasonic GH4 body and tried the same procedure, only to get the “lens attachment failure” screen each time a lens was attached to the Speed Booster. At this point we were convinced the problem was the Speed Booster. My cost to send the unit to Hong Kong and back for repair was over $60. This means I’ve spent over $700 for a unit that does not work, even after an attempted repair. I can’t tell you how demoralizing this is.

[@kuntaleroy7414]

FINAL UPDATE: I received a replacement Metabones Speed Booster from B&H Photo today as a solution to this problem. Of course I was anxious to mount the adapter on my GH4 camera body and start the testing, and that’s exactly what I did. The adapter was initially mounted on the camera body and the camera was turned on. The first lens I mounted was the EF 17-40mm f/4L and immediately the mount worked. The GH4 accepted the lens and was fast and accurate in processing focus info from lens to camera to lens. The Speed Booster and lens combo also resulted in an apparent 1.5 stop increase in the lens aperture, allowing me to shoot 4K video inside my home office under relatively low light (1 small lamp) at 1600 ISO and get excellent perfectly usable footage. Next I mounted the EF 70-200mm f/2.8L mainly to test the autofocus accuracy and the GH4 / EF lens response speed. The combination worked flawlessly with fast accurate focusing even in that low-light situation. I dare say even new Lumix lenses equipped with internal memory of bokeh files to use with the GH4’s new DFD focusing technology would, at best, produce only minimal increase in this focusing speed. This is, of course, what makes all the hassle I went through worth it. Thanks B&H!

[@Bilbainutxo22]

and Canon lenses? you can also use Metabones? What would be the model that you recommend for canon lenses?

[@TVBlackStone]

thx for that was so good for me to see that but what about foucas with speed boster will be manual or aouto fast or slow ? thx alot.

[@CaptainRon85]

Great video Max. Thanks for sharing!

[@TheReelLifePerspectiveShow]

Hey Max, Thanks for this video. So do I need an adapter to add this speed booster to my gh4? I'm attaching it to my 7-14mm wide angle lens I got. Or is all I need is this speedbooster and it will attach just fine without an adapter?

[@tptrsn]

As far as the shots of the bridge with and without the speed booster, was there a difference in white balance, or does the speed booster add a green cast? I thought the greenish hue of the concrete really jumped out in those shots, but I figure it was a white balance adjustment somewhere along the way, like maybe you shot with the speed booster first, and then realized you needed to white balance when you were switching to the regular adapter or something...?

[@MaksimYuryev]

I don't think its the speedbooster. Camera was in auto white balance the whole time so I'm guessing that's why. Sorry for the confusion my bad!

[@JoshuaFaleatua]

Hey this might seem like a stupid question. But if you attached the speed booster to a GH4, can you still use a MFT lens while the speed booster is attached on just to get more light and wider shots with the MFT lenses. Or is it strictly e-mount lenses with the speed booster?

[@felixkuehl]

Does the adapter control the build in aputure of the nikon g lens or does it have an own build in aputure?

[@EstebanBustos]

Hi max, which is the best speedbooster for the gh4?thanks

[@williamvanboening2341]

i am looking at the gh4, i am new to this side of the art of video.I am a professional tattooer and shop owner for 25 years and want to pump up the image of my shop.I also have small films i am wanting to do and editing on DaVinci Resolve . how good is the g7? i do like low light function for bar shoots live band etc. so much out there.

[@alexpinedafilms2227]

Hello, excellent review. But i'm a little confused. So this means if I use a canon lens 50mm with the adapter it will be actually 80ish mm?..If I record video in 4K it will be the same crop results as if in FULL HD?..I saw you used a 50 mm nikkor and it looks wider with the adapter, but for what I searched on line, or for what you said at the beginning of the video, it shouldn't be wider, (50mm to 80ish mm). I would apreciate your answer..And also, will it be the same with the "S"version?

[@solvaij]

Great man i will get one of this Speedbooster

[@ceediqmoh5486]

Hey max, thanks for your video. Have got a Carl ziess zf lens will it work the metal bones and GH4?

[@MaksimYuryev]

Is it like this one? amzn.to/1vBdwtC with this mount it should work great!

[@thomastmic]

Great video! Why didnt u go with the bmpcc speed booster for the gh4?

[@MaksimYuryev]

At the time I ordered it no one had yet tested that one on the gh4, and while it does work it leaves a "ring" on your shutter. There is some risk of breaking something if you don't have it set to electronic shutter. I may go for it in the future we will see :)

[@joahcolby]

Hey Max thanks for the video! I have been experimenting with photo style settings on GH4 but have not found a winning combination. What would you recommend for best DR performance with acceptable amounts of increased noise? Thanks!

[@MrFlipatrick]

[@verybang]

Are there any speedboosters for MFT lenses instead of EF and nikkor?

[@TURST67]

Hello, I'm currently using a Canon 600D with a Sigma DC EX HSM 30mm F/1.4, what will be the "new" aperture if I use it on a GH4 ? Do you recommend me to use this lense with it ? I really enjoy it with on my 600D

[@MaksimYuryev]

Yes. It will be about F1.0 (but camera will still read F1.4 because the Gh4 won't let it display that low)

[@ShadowEMedia]

thank you for the video, i have a sigma 18-35mm 1.8 lens for my gh4 with a nikon f mount and its terrible in low light what speed booster would you recommend? i also use the kit lens from d3200

[@MaksimYuryev]

I'm not sure why it would be terrible thats one of the best low light lenses. I would recommend the Nikon mount because those are your lenses.. The kit lens lets in WAY less light than the 1.8 sigma.

[@ShadowEMedia]

the lens is great when i use it on my nikon d3200 in low light its perfect but when i use it on my gh4 its completely dark even with my led lights on so i was thinking it may be the mount

[@MaksimYuryev]

ShadowE Media what adapter are you using? Does it have aperture control? If not then the lens is stuck at F22

[@ShadowEMedia]

Max Yuryev AST New Nikon F lens to Micro 4/3 M4/3 Camera Mount Adapter adaptor ring www.amazon.com/gp/product/B00A9Q7H9M/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

[@MaksimYuryev]

ShadowE Media Yes that is for Nikon "F" which are the old manual lenses that have aperture built in. Its the same mount as the new "G" so your Sigma 18-35 1.8 G lens fits but the "G" lenses don't have manual aperture you need an aperture bar to adjust it. I have one of those adapters as well but it's only good for manual lenses. This is what you need to be able to control your aperture goo.gl/MtpqGb ( I have one of these as well) or if you want the speedbooster that I talk about in this video it's here: goo.gl/ysz2o9

[@adventuroustravelearth5493]

I have Panasonic GH4. I use 3 Voigtlander MFT lenses with it. I also have vintage Prime lenses like the Nikon Nikkor 50mm F/1.8, Pentax SMC 50mm F/1.2, 50mm F/1.7, then Olympus Zuiko 50mm F/1.8, 35mm F/2, 28mm F/2.8, 100mm F/2.8, 135mm F/3.5, and 35 to 70mm F4 Zoom. I don't know which Metabones adaptor to purchase due to the wide variety of lenses I use. Any suggestions?

[@garyking4032]

Hi Max, Thanks for the very useful video. However at 4:14 you say the speedbooster helps give you a narrower depth of field, and this isn't the case. Until I researched it more deeply, I assumed that going from 1.8 to 1.2 using a speedbooster would narrow the DOF but it doesn't in this case as the DOF is an attribute of the lens. The extra stop is very useful for low-light shooting though :)

[@MaksimYuryev]

Thanks Gary! you are totally correct. I was under the same impression when reading up on it but now I understand how they meant it. If the lens is wider you can come in closer which will in turn give you shallower DOF. If you need the lens to be wider to get your shot and you stay in yhe same position it wont be shallower dof just a wider shot.

[@garyking4032]

Max Yuryev I've got to admit, I find the whole speedbooster/DOF thing a bit confusing. Either way, I hope to get an EF to MFT version if I go to GH4 as it looks like a great bit of kit. Thanks again for the review.

[@Gmoneyfly]

Hey thanks for the video i just have a few questions..I have a canon t2i with tamron 17-50mm f/2.8 lens I'm using on it but Im bout to buy the gh4 and i want to use the lens i already have. whats the best speed booster you think i will need and how do you think the tamron lens will do on the gh4 far as quality and low light????????

[@MaksimYuryev]

the Tamron will do well! you need the EF to M43 speed booster it will even support the IS. I have a video on it with links you can check it out.

[@Gmoneyfly]

Max Yuryev thanks for the respoces cause i was kinda cunfuse i aint know if i wanted to just buy at gh4 lens when i buy the camara or just use the tamaron

[@NathanielBarberMotionPictures]

Max, I've recently purchased the Gh4 with the speedbooster and a sigma 18-35 mm lens. I'm having difficulty balancing it on my glidecam hd 2000. The camera seems too top heavy. Would you know how to balance this rig?

[@robsquad_films]

With the 18-35 can you stop down with the lens having a non-manual aperture? I can't find this question anywhere.

[@MaksimYuryev]

Yes. With EF to M43 speedbooster you do it in camera, with Nikon G to M43 speedbooster it has an aperture ring on the SB where you can adjust it.

[@rborroto]

For those who cannot afford a $400 plus lens adapter, there are Chinese knock-offs made by Zhongyi Optical called Lens Turbo. The optics are not as good as Metabones, but they're around $100 bucks.

[@MaksimYuryev]

Better than the fotodiox yes, but when you buy a $1700 body + lenses I would suggest to save up a bit and buy the Metabones.

[@raredreamfootage]

How does it affect focus distance (i.e. minimal focus distance vs infinite) and focus breathing?

[@castorinaphotography]

Is the crop factor the same whether you use the metabones with a Nikon dx or fx lens?

[@CubeMediaTV]

Thanks man! I am planning to buy GH4 what do you recommend me to do with audio ( record with rode NTG-2) and i want to record directly to the camera A cheap method please

[@MaksimYuryev]

It seems that you will need to use some kind of external recorder and then go into the camera as the ntg2 need phantom power. The cheepest method I can think of is use the Tascam DR40 and use the headphone jack to go into the camera. Or you could sync in post, but in would look into that more. amzn.to/1hLdndE amzn.to/1oNVGyY another good option is to get the powered rode videomic pro and use that for regular shooting when you don't want to deal with exra recorders, but when you want the beat sound go with the full setup amzn.to/QHXe1m

[@Kutkop345]

i was wondering which regular (non-speedbooster) adapter you are using on the gh4 for the sigma lens. Trying to find a low price flat adapter besides the metabones speedbooster

[@MaksimYuryev]

amzn.to/1hUlA5i it is this one but I wouldn't recommend it because it doesn't have aperture control. I would suggest the regular metabones adapter that doesn't have the speed booster element in it. Its about $140 and has the de-clicked aperture and is very good quality. amzn.to/1ltBQsU

[@Kutkop345]

Max Yuryev Thanks :)

[@juancarlosmedrano9512]

I've spent nearly USD 500 in the Metabones Speedboster and I have to say I could have saved that money. It works well only from f / 1: 4 to f/ 1:11. At f / 1: 2 or less to f / 1: 1.4 only works well in the center of the image. At the sides and corners is very, very soft and provides chromatic aberrations. The extra stop is useless and is better to spend that money on a good native lens. I am outraged that Brian Caldwell told me that the problem is the lens Canon FD 50mm f / 1: 1.4. It is incredible .....

Just watched your video and it looks like the speedboster is a real piece of nice equipment! I'm looking to buy a GH4. I've used a Canon EOS 550D and a Sony RX100M2 in the past. I have no lenses anymore, so what brand of lenses would you suggest using on the GH4 with the speedbooster? I will primarily use it for video and then some stills. Maybe 80% video and 20% stills. The ones you suggest in this video does not have stabilization on them. Doesen't that make shooting video a bit hard? I'm thinking two or three lenses; wide, medium and tele.

[@markstanley2001]

Hi from Nova Scotia - thanks Max for this video and for your website GH4 Shooter! I have the GH4 and I'm an amateur videographer. I also live stream special events here in my hometown but I have a problem: I'm a confused amateur as far as lenses are concerned. I'm looking for a good low light lens for the GH4 with OIS...will the speedbooster be compatible with anything? Will I need additional Speedboosters for different lenses on the GH4?

[@MaksimYuryev]

wayne william The new EF to M43 speedbooster is out and it supports image stabilization! :) check out my latest vids! it would be perfect for you!

[@Entwamessage]

What do you do about focusing? And do you know if the GH4 can be hooked up to a laptop to be used as a monitor when filming?

[@MaksimYuryev]

Yes you can use external monitors while filming with the GH4, even wirelessly with the panasonic app you can download for Android or IOS. I use manual focus and use the focus peaking options in the GH4

[@Entwamessage]

thanks so much. what is the focus peaking option? I haven't found that yet.

[@MaksimYuryev]

Entwamessage It will put little flashy dots on the areas of the image that are in focu, so it make it much easier to see when your in focus :)

[@JamesOrlowski]

Curious about the GH5 and Speedbooster compatibility. Since the GH5 doesn't shoot "crop" when in 4K like the GH4 did, which Speedbooster would be more appropriate for Canon lenses on the GH5? The XL or Ultra (or neither)?

[@MaksimYuryev]

My guess would be the ultra would be the best choice, since XL is designed for the Gh4's 4K crop mode. We'll only know for sure when someone can test this with a variety of lenses.

[@MaksimYuryev]

Your guess is as good as mine so you may be right, but we'll see when we get samples.

if I use the speedboster with another lens with a 30$ adapter, will the quality break down? I don't want to buy a speed booster for each type of lens.

[@lukaskusstatscher6007]

hey man, nice vid! I was just wondering what the 11-16 tokina turns to, using the metabones adapter? Im actually shooting lots of sport and therefore I´m afraid not to get a wide shot using the gh4... thx for your help

[@MaksimYuryev]

do you want to know in full frame equivalents?

[@MaksimYuryev]

In full frame equivalents shooting 4k you get 17.9mm-26.7mm if shooting 1080p you get 16mm-24mm

[@lukaskusstatscher6007]

Max Yuryev thx for your help dude! got another little question: does the canon FD to four thirds adapter work for all canon lenses? thx for helping again

[@MaksimYuryev]

lukas kusstatscher no prob! The Fd to m43 only supports canon fd lensew which are the older manual ones not the modern ef or efs lenses that have autofocus. So you need and ef to m43 for lenses with autofocus

[@JackBenziger]

Hey Max, Was wondering if you could tell me what the exact focal length is on your GH4 when you have the Metabones speed booster on with the tokina 11-16mm. I have been looking everywhere but can't seem to find the answer. Keep on the good videos, I enjoy them soo much.

[@MaksimYuryev]

Thanks Jack! I'll explain the way to find the focal length just in case you want to find out other lenses on the booster. The speedbooster makes lenses 0.71 wider, so 11mm x 0.71 = 7.81 . Now you introduce the sensors crop factor. If your shooting 1080p its 2 if shooting 4k its 2.3 . So take 7.81x2.3= 17.96mm on the wide end (11mm) so same for 16mm. 16x0.71x2.3=26.1mm . Tokina 11-16 on a speedbooster with gh4 shooting 4k is equil to 17.96mm-26.1mm full frame equivalent. If your shooting 1080p or photos you have 15.62mm-22.72mm. I hope that helps!

[@JackBenziger]

Max Yuryev yes that helps so much thank you!

[@Scubastevesatt]

Hey Max, very helpful video man. Thank you. I'm looking for a standard cheap adaptor, which one did you buy and use?

[@MaksimYuryev]

thanks! I have a fotasy brand adapter with aperture control.

[@Scubastevesatt]

+Max Yuryev Great! Much appreciated.

[@andrewvega9101]

I would love to buy a Magic Speed Booster! Max, do you know if the adapter shown will work with my Nikon DX lenses? Please and thanks, Andrew

[@MaksimYuryev]

+Andrew Vega Yes the regular version will, but not the XL version. Thanks for watching and subscribing!

[@ZenjoewalshMedia]

I have a Sigma 18-35mm for Nikon, and i use an adapter so I can put it on my GH4. But the aperture ring seems to be very loose and when I open up the aperture, it automatically closes again. This is very stressful and was wondering if this metabones adapter would be able to hold the aperture open on the Sigma 18-35mm?

[@MaksimYuryev]

Yes. The metabones is a high quality adapter works great.

[@ZenjoewalshMedia]

Thanks

[@keneakins]

This isn't really like having two great lenses. It's more like getting one really sharp lens, and one not so sharp lens. The focal reduction actually sharpens the image more, as you're essentially reducing the entire field of view down onto the smaller sensor (a bit like downconverting). The normal adapter will still make the sensor crop into a small section of the lens, which isn't as sharp.

[@SR22T_Pilot]

Hey Max! Did you check this booster with Cheap options? What the difference? I am going to use nikon lenses, so i do not need chip in speed booster..

[@MaksimYuryev]

+Victor Baars Yea I did compare it to one adapter. Check my channel (fotodiox)

[@SR22T_Pilot]

+Max Yuryev Thank I will!

[@williadriani5542]

I'm taking mostly photos (not video) on Olympus E-M1: are there any comparison shots between E-M1 + Speedbooster + Tokina 12-24/4 or 11-16/2.8 versus E-M1 with the micro43 lenses Olympus 9-18/4-5.6 or Panasonic 7-14/4? Because I come from Nikon DX (APS-C) to mFT I already have the Tokina 12-24/4. It would be much bigger and heavier than the two native mFT lenses, but I'd only need to buy the Speedbooster. Is the image quality of one of the Tokinas plus Speedbooster in the same league as the two mFT lenses, or better or worse? There'll also be that proposed Olympus 7-14/2.8, but a) it's not yet out and my vacation starts soon, and b) it'll probably be quite expensive. I couldn't find real comparisons with example images anywhere.

[@MaksimYuryev]

Willi Adriani I doubt you'll find those comparison. Not very many people use the SB for the Olympus cams, and its mainly used for photo. The M/43 lenses are really sharp so i'd say most likey that would give you better image quality than using a SB and Nikon glass. If its not better it would be even. Keep in mind with a MB-SB you won't have autofocus.

[@Perfectpixtures]

i have canon lenses 24-105 F4 L IS USM, and 1.8 50mm and i want to buy GH4 can the metabone speed boaster work well with them ? because i might not buy the sigma 18-35 because of budget

[@MaksimYuryev]

+Perfect Pictures Tv Yes it will work!

[@fbarrabino]

Hi Max! Big fan of your videos! I know you are an expert on gh4, so here´s my question: Regarding metabones speedboster XL, should we expect any issues with the upcoming gh5? Auto focus, vignetting? Do you know how will it behave in 4k, now that the crop is gone? I would much appreciate your thoughts on this matter. Many thanks!

[@danjones4002]

first off great vid.. right now i have a G6 that i use with a kit lens and a fd speed booster with some vintage primes. i'm thinking i'm going to get the the new EF speed booster. the main reason for this is to gain IS. my only concern is, i really like the sigma 17-50 but im not sure if the 1.4 crop factor will cause the corners to clip/vignette seeing is is designed for a 1.5 crop camera? i know that on the gh4 in 4k this wouldn't be a problem, but do you know if shooting in 1080 it causes problems?

[@MaksimYuryev]

Hi Dan, I tried it with my Tamron 17-50 2.8 and is very slight vignette when shooting photos at 3:2 or 4:3 formats but not when shooting in 16:9 / 1080P (maybe very very slight amount) but I'll let you be the judge. Here is a link to test photos of me shooting at a white wall, both @ 17mm and 50mm. In each focal length photos with 4:3, 3:2, and 16:9. This is at the 2x crop or 1.4 like you said using speedbooster, of course if you'll be shooting 4k it will be more cropped in. goo.gl/tY920O I know this is not the Sigma 17-50 version but my guess is it will be a similar result. The Tamron is also a great lens and from what I remember when researching it has slightly better image stabilization but its louder than the Sigma version. I've had both the Tamron 17-50 2.8 VC and Sigma 17-50 2.8 OS in EF mount, but at different times so I can't compare them side by side, and at this time I have a Tamron 17-50 2.8 w/o VC for my Nikon speedbooster. Hope that helps!

[@tkmslee]

Max. What other settings are you supposed to do to your camera when using the metabones adapter? I did set my "shooting with lens off" setting on. But now I think my camera is busted...it keeps making an electronic noise and the screen blinks and settings reset each time. Was I supposed to set the Electronic shutter or something? Thanks!

[@MaksimYuryev]

With the Regular speedbooster all you do is set it to shoot without lens. I would not reccomend the BMCC or BMPCC ones. What one do you have?

[@tkmslee]

I have the regular m43 with Nikon mount.

[@adventuroustravelearth5493]

Can this metabones adaptor be used for voigtlanders 10.5mm, 17.5mm & 42.5mm F/0.95 Lenses on a GH4

[@TomPalissade]

Hi Max There is something that messes me up, how do you calculate that your 50mm FF is gonna be an 84mm lens? I'm using like you a 11-16mm APS-c Tokina lens and I'd like to know how much I'm going to get in final. As this metabones adapter is now discontinued, can you tell me, if you know it, what make the difference with the new ones, XL 0.64x and the ULTRA 0.71x? I intend to buy this 2014 model on the second hand market and I wonder if it's worth it ($290) Thanks Thank You

[@TomPalissade]

+Kai Leingang Thank you very much for your answer, much appreciated 😊

[@jamdanseur20]

Hi máx i from colombia, i want buy the gh4 but i have semi auto nikon lens, this lens work with the speedbooster? Thanks

[@MaksimYuryev]

Yes All nikon lenses (G mount and F) will work!

[@NoAnchorTV]

Nice shotgun. I do need one of these though haha

[@redbully6389]

max can you help me please?? i buy the gh4 but i have canon lens, do you think it will work as fine as if it was a panasonic lens? what speed booster you recomende for me to buy??

[@MaksimYuryev]

If you want to use your Canon lenses you need this one: goo.gl/vJTpcb

[@marksawatzky3440]

Great video Max, it's kind of confusing when it comes to depth of field here, I have been adapting lenses on all the Panasonic GH cameras for some time with Canon FD, I have a speedboosting adapter as well as a 50mm f/1.8 but I also have the Panasonic Leica 25mm f/1.4 . I am going to make a video today that compares the depth of field each can achieve at f/1.8 but if I had to guess now before doing an actual test I suspect the Panasonic Lens is going to win really hard. And if I open up to 1.4 on the Panasonic I strongly suspect it will beat the 50mm 1.8 speed boosted for depth of field, but definitely check my channel later tonight for the upload, maybe I'm wrong! :)

[@MaksimYuryev]

Thanks I'll check it out!

[@Spencer635]

Hey max, been watching your video for a while, great stuff btw man. So I got a gh4 a few months ago with an olympus 12-40mm and every now and again when I power on the camera it tells me 'lens attachment failed'. I'm trying to figure out if it's the lens or the camera having problems and how to fix it. If you have any advice I'd love to hear it.

[@MaksimYuryev]

Hi Spencer. Do you have any other lenses to test it with? It's really hard to know. You should join the GH4 user group on facebook (almost 4000 members now) and ask if anyone has had a similar issue.

[@moreapropos]

Thanks for the video. I was curious about one thing. So in determining the actual focal length, you are multiplying the sensor's crop factor of 2.3 x focal length (50 mm), to get 115 mm, then multiplying by the focal reduction of the booster, .70, to get 80mm. Is that correct? Now if someone was using a DOF calculator to assess hyperfocal distance or something like that, they would plug in 80mm for the focal length, correct? It is all just a little confusing. Thanks!!!

[@MaksimYuryev]

+Flying High that would be tough. I think you would use the focal length of the lens the way it is the the sensor size after being converted. If you have the speed booster XL I would do a 1.5 crop so use a Sony a6000 of something, but if you have the regular SB like I do you would be at 1.7 or so equivalent. I know Canon crop sensors are 1.6 not sure if there is a sensor that's 1.7.

[@patrickfitzgerald2861]

It doesn't matter how you arrange the math in the calculation: Focal length (mm) x Speed Booster reverse crop factor (.71 in this case) x sensor crop factor (APS-C: 1.5, Canon APS-C: 1.6, MFT: 2, or 2.3 in GH4 4K). So: 50mm x .71 x 2 (MFT) = 71mm FF equivalent field of view. You use the same calculation to determine FF equivalent depth of field, except you substitute aperture for focal length: f/1.8 x .71 x 2 (MFT) = 2.556 FF equivalent for DOF purposes. You leave out the crop factor multiplier only when calculating the boosted aperture: f/1.8 x .71 = f/1.278. Hope this helps.

[@MrDilipdilip]

Patrick Fitzgerald hi, do you know the canon 24-70 f2.8 will work using this metabones?

[@V3Tv]

Well as this video and the products are so old, I know it is unlikely I will get a quick response here if at all, but here goes. So I have a GH4 and finally got the speedbooster in the mail yesterday so I can use my Canon & Sigma lenses. I am hoping that I am just doing something very noob style as there is no way this issue can exist after so long. But when I try to use the camera, the autofocus just keeps going crazy, it won't lock. And even if it gets (somewhat) locked in on an object it will then just flicker the focus and the lens will just stutter ultra fast. Obviously this only happens in auto focus. Is a setting on the camera in need of an adjustment, or have I just received a faulty unit>? Thanks

[@MaksimYuryev]

Hey! Idk if its faulty but the GH4 is bad at autofocus even with factory lenses so you basically need to use MF.

[@V3Tv]

I had a feeling that was going to be the answer. Thanks for the speedy reply Max

[@yankeetronaldo4286]

Is there any other adapter apart from metabones which goes with all the lenses.

[@thesixdigital1625]

+Yankeet ronaldo Yes, just search for a standard Micro 4/3 adapter. Nikon or Canon. Check out my page for 4K GH4 videos. (Speedbooster test)

[@redstarkrasnodar]

will it work on autofocus lenses not on CANON?

[@Mrcherrardcohen]

Is there a speedbooster for Micro 4/3 lenses?

[@planetearth1357]

Hi ..iam new to photography..how can i have that wide angle with my olympus 25 1.8 can i use a metabone..and another question. Is there a solurion to have an optical image stabilizing other than buying a lense with a stabolizer?? Thanks

[@MaksimYuryev]

Hi there. The Metabones speedbooster only work by taking a lens designed for a larger sensor and magnifying the light down, so you can do micro 4/3 to micro 4/3, It needs to be a Nikon or Canon lens to M43. As far as image stabilization for the most part you have to get a lens that has IS, but there are some olympus camera bodies that have image stabilization built into the camera body. Hope that helps!

[@planetearth1357]

Max Yuryev My camera is gh4..and I need a wide angle lense like the images you showed ..whats your advise shoud i buy a metabone or there are a good wide angle lenses in the market..Buy the i like your review they are simple and to the point..

[@MaksimYuryev]

planet-earth123 Thanks! the speedbooster is a good investment if you want to use multiple lenses with it, but if your buying it just for one lens it may not be worth it. This is a great native lens but its not as fast as the SB+11-16 setup amzn.to/1ySq40e . If you want to go with what I have, use my speedbooster link above to get that and then pair it with this lens: amzn.to/10ghr3f You get same zoom range as that panasonic lens but its F2 instead of F4

[@planetearth1357]

Max Yuryev thanks alot..

[@planetearth1357]

Max Yuryev Whats your thought on this Metabones (Nikon G Lens to Blackmagic 2.5k Cinema Camera with Micro 4/3 )...

[@thisisclaire5860]

I'm confused. When you put the speed booster onto a MFT camera (GH4) can you still use a MFT lens? Or do you need an EF/FF lens?

[@MaksimYuryev]

+thisisclaire Yes you need to use an EF lens. Thats how it takes the larger image from the larger lens and "scaled it down" to provide more light to the sensor.

[@Torrefuertes]

Can I use this speed booster for GH3

[@upmg1903]

im planing to buy a gh4 but i have some canon lenses would the speed buster help to use thesis canon lenses ? can it be any speed booster to be able to control the iso and aperture ?

[@upmg1903]

i have a canon tokina 11 -16 mm and the sigma 30mm

[@MaksimYuryev]

upmg1903 Sorry Only nikon lenses for now.

[@noreaction1]

I thought the mft crop factor was 2.0, so wouldn't that make a 50mm lense appear to have a 100mm focal length and not 115mm on the gh4? Am I missing something? I'm kind of new to this

[@MaksimYuryev]

in 4K video mods it's slightly more crop. (2.3) than in photo or 1080P video mode.

[@Feuilledautomne-arbredhivers]

Hello Max, Could you tell me wish camera were you using during your presentation (when you speak) Please ? Did you see that there is some "moire" at youtube 4k resolution ? How would you explain that ? Thks for the answers !! Ps: I'lm French (sorry for my English)

[@MaksimYuryev]

Hey Germain! It was the gh4 with 4k! I dont know if youtube compression will add any moire? The speedbooster had been noted to add a very slight amount of moire as well. I honestly didn't notice it until you said it, (and you mean on my shirt right?) This shirt also moires like crazy with regular cameras! Check out this vid where I wear the same shirt using a typical canono crop sensor (horrible) Part 2 - 2013 New Mac Pro vs Custom Build PORTABLE PC " The Mac Pro Killer " - The Build - U3 TITAN

[@MaksimYuryev]

Also something I noticed that when you view 4k on a smaller than 4k screen it introduces moire as well because of the not very good algorithms. If I view the video in the 4k setting full screen on my 1080p monitor the moire is very slight, I almost don't even see it, but if I have it not in full screen mode there is a crazy amount! I think thats just how youtube scales it.

[@Feuilledautomne-arbredhivers]

Thks Man !!!! Hope you are going Well !

[@Check-it-out]

With the Speedbooster you will loose single point autofocus right ? And i can't find one for Canon lenses, which i have. Cool video, get rid of the gun !

[@eltawtee8104]

is there any speedster for panasonic 12-35mm f/2.8 lense for gh4?

[@MaksimYuryev]

No you have to use a larger lens with a speedbooster, like a Nikon or Canon lens.

[@AmrToukhy]

Will this adapter work with the new Canon EOS M5?

[@matthewcopperpot229]

Can you please show us some example shots using that gun behind you

[@simonwilliams7850]

lol Excellent wit!!

[@davidalanmedia]

Have you tried the Nikon 14-24 with the GH4? I have the Metabones adapter and it works well with the Nikon lens but would like to pick up a Speedbooster.

[@MaksimYuryev]

Nope I havent. I use my 11-16 Tokina for wide. You'll love the speedbooster It will make the lens wide again :)

[@HorseHeadAntimatter]

hey Max, with the speedbooster: does the lens' Image Stabilization still work?

[@MaksimYuryev]

Hey! it works with the EF to M43 one goo.gl/vJTpcb but not the Nikon G to m43.

[@HorseHeadAntimatter]

Max Yuryev Thanks Max!

[@HorseHeadAntimatter]

Max Yuryev Now after working with the GH4 for more than five month are you still satisfied with it?

[@MaksimYuryev]

HorseHeadAntimatter Yes! :)

[@mohdpazli]

nice review.. but couple of wrong info.. it will not become f1.2 FOV (50/1.8 + speedbooster).. the light transmission is correct (1.8 x 0.7 = 1.26).. it will not have have depth of field of f1.2 from a fullframe camera equivalent.. you need to multiply with the sensor size also which is 2x crop (gh4).. 1.26 x 2 = f2.52.. so micro4/3 + speedbooster + nikkor 50/1.8.. you will get an equivalent lens of 70mm f2.5.. there is a lot of other alternative, to name a few.. zhongyi lensturbo, kipon baveyes

[@MaksimYuryev]

Thanks for your comment. As far as the aperture in dont think I said or I didn't think I meant to say a F1.2 dept of field full frame eqiv because of course the smaller sensor has way more in focus. Just the f stop becoming F1.2 as far as light transmission when compared to the F1.8 (All for the M43 eqiv not full frame) because the lenses are still rated at same fstop as far as light transmission that the sensor will use correct? I'm aware that F2.8on m43 will be like F5.6 on full frame when comparing dept of field, not the exposure of the image. Hope I explained myself well!

[@Elmercuaton]

is Metabone use only for GH4 or can use other camera? like Sony A7s2?

[@MaksimYuryev]

A7s2 is a full frame so no you can't or it wouldn't make sense. If you have the a6300 or a7Rii shooting in super35 then it would be useful.
