VILTROX EF EOS M2 SPEEDBOOSTER PICTURE QUALITY TEST with Canon M50. Buy adapter or speedbooster?

[@ZdenkaDarula]

Thank you for watching. As it turns out I totally forgot about the sensor crop on M50 so please multiply the numbers with Speedbooster further by 1.6 to get the final focal length... we are humans and make mistakes 🤗. So 50mm with speedbooster gets you 35.5mm but then M50 crop multiply by 1.6 and you get 56mm..... Which one do you have? Adapter, speedbooster or both? How is everyone enjoying the camera and what did you shoot this past weekend? Wishing everyone amazing week!!!!

[@34Media]

planning the high speed challenge, no adaptor yet saving up for 11-22 m lens first before i worry about other glass.

[@cooloox]

Hi Zdenka, nice video, as always. Just one little thing: the 50mm lens usually acts as an 80mm equivalent lens on a Canon crop sensored camera(50mm x 1.6). Therefore, using it with the Viltrox Speedbooster it becomes a 56.8mm equivalent lens (80mm x 0.71). So it's still cropped in on an M50, but much less so than with the standard adapter. It looks lovely where you live. Have a great week too. Your eyes are looking good, I hope that means you're not having too many issues with them right now. 🙂

[@photography.by.James.Wood.Jr.]

I have only the adapter but will be purchasing the speedbooster real soon. Thanks for the video!

[@ZdenkaDarula]

Good for you... I don't have wide lens myself and truthfully I really never needed it as I always do mostly weddings and portraits...

[@TheImprobableIronman]

I have to say that it's refreshing to find a review based around what the output actually looks like. Nice job.

[@ZdenkaDarula]

Thank you very much. 😊📸🎥🎬

[@matzilb]

Thank's for the explanation I wait for you all the past week... But I think it's 50X1.6 = 80mm, 80X0.71= 56.8mm. So It's almost full frame Camera!

[@ZdenkaDarula]

yes that is right... you have to apply further crop on M50 1x6.... Viltrox crop is 0.71

[@Anthony2lars]

That is why it way better if you have both adapter and speedbooster. Its like you have 2 prime lens in one. Hahaha

[@legacyfitness7469]

I have both, I like the speedbooster better for the extra speed in low light

[@ZdenkaDarula]

I think I am the same way. I use the speedbooster more... cheers 📽📷🤗

[@VioletHenning]

Very nice comparison with the two cameras to show the difference with amd without speed booster. I see what tou are saying about the images being a little bit softer with the speed booster but what struck me most is how you manage to get both photos so similar on an expensive and not so expensive camera. A true artist.

[@ZdenkaDarula]

Nope not true artist... kush exactly same settings on both cameras 🤗🤗 you know it is scary that this cheap camera is almost the same like the camera I paid over $2,500 back then.... I think I am done with those very expensive cameras... I'll just wait for something in the middle price range... or just wait until smartphone cameras take over 😁😁😁 which will happen adventually

[@VioletHenning]

Someone told me omce if you cant make good pictures on a cheap camera then you are wastimg your money on the expensive one. I was thinking about the EOS R for christmas.

[@ZdenkaDarula]

That would be fantastic choice... BUT wait... there is some new camera about to come out from Canon I know people are talking about it lots... just wait for little. I would get the R too but I am also waiting for the new one.

[@VioletHenning]

Is it not the 90D? It has crop sensor and is not mirrorless if i am correct.

[@CaravanMovies]

what happens if we use speed booster in full frame camera like EOS R ?

It is not for full frame cameras 😊🎬📸🎥

[@MaxMastery]

I would say with personal experience in travel that the Speed Booster with video usage is great. The 1080 setting FHD with Speed Booster will be beneficial more with the fact that you can step down the 1 stop in the aperture. Again I understand that this video was about photo quality. My comment is to those of us that are more about video usage with the M50. That being said, in the video setting on the M50, there is no noticeable softness because of the lower and fast motion. I personally would not use the Speed Booster with photos, as the regular EF adapter works well. Great video! I love what you do and always looking forward to more videos from you.

[@ZdenkaDarula]

[@AltCine]

Very good test! That's the key with speedbooster....you don't have to always shoot wide open, the fov is a bonus by itself. I tend to only go wide open in very low light or for backgrounds that I want blurry. So many people say negative things but it's just another tool and you need to work out the pro's and cons.

[@ZdenkaDarula]

totally agreed. That is why I said in the video to make decision on their own... it is personal opinion... lots will say no and lots will say yes... great comment.

[@RanjithCoplay]

I think the speedbooster should be used only for scenarios while shooting 4K on the M50. 4k by default has a 2x crop factor in the M50. When you use the speedbooster, it roughly brings it down to 1.42 approximately.

[@ZdenkaDarula]

Yes that is good use as well. For me it would be that and also low light. It helped me when I was testing it at wedding

[@Renegade1127]

One thing nobody mentions about the speedbooster is if it affects Minimum Focus Distance. Do you know? P.S. focal length : 0.71 booster * 1.6 crop = 1.13, so 50mm * 1.13 = 56.5 Old soldiers never die - just like this topic 😊

[@ZdenkaDarula]

Yes that’s correct

[@Trader-CL]

Thanks for the great comparison! Just like to point out it's not f1.2 for the speedboosted f1.8. It should be 1.8 x 1.6 (crop factor) x 0.71 (speedbooster factor) = f2.0. The reason you see more bokeh in the speedboosted lens is because the 50mm lens becomes 56.8mm (50 x 1.6 x 0.71). The focal length is 6.8mm longer giving a shallower depth of field. Also the standard 50mm f1.8 is one of the worst performer in the entire Canon range especially when wide open.

[@ZdenkaDarula]

Yes this has been addressed many times in previous comments... thanks

[@spandsbab]

Softer photos on 100% crop and a little vignetting vs wider view and 1 stop of light to me is a no brainer... instead of spending $1.5-2k in the Eos RP with 1 lens and just half of that on the M50 with more EF lens is just an easy pick... speed booster for the win!

[@ZdenkaDarula]

Thank you very much for sharing your thoughts. 📸🎥😊🎬

[@wildopen3302]

03:00 you need to consider the crop factor of the camera. example 1.6 crop factor x 0.71 x 50mm lens.

[@ZdenkaDarula]

Yes that’s right. The talk was only about the Speedbooster though 😊🎥📸🎬

[@MSGRetired]

I am just getting serious about photography. I have both the adapter and speed booster. My DSLR is an older Canon 50D. I love the new M50. I do lots of motorcycling in the summer and take tons of bike pictures. Your videos are helping me a great deal. Thank You !

[@ZdenkaDarula]

You are very welcome. I am very happy that these videos are helping. Many greetings back to you

[@geru2000]

Thanks for another great video on the M-50. I didn't pick up a speed booster, I do have a lens adapter though. I assumed that the speed booster would affect the sharpness of the photo's but it seems it is really minimal and mostly in the corners. I think I'll stick with the lens mount adapter. I've shot crop sensor since I began with photography so I really see no reason to purchase one even with the additional advantage of the 1 stop of light with the speed booster. Aren't kids fun? My youngest is 44 but we have grandchildren and great-grandchildren ranging in ages from 5 months to 27 yrs old. Love them all and really glad they don't live in my house. I love for them to visit but I also love for them to leave, unfortunately not an option when they're your own. Enjoy it though the time goes by so fast soon they'll be entering college and you'll be wondering where the time went. Best to you and yours and again thank you for the time you put into these videos they are very helpful.

[@ZdenkaDarula]

Hi Jack. Thank you for your great comment. Yes I do agree with you. I bought the speedbooster because I already have all the lenses. But adapter is great because it gives you such different focal length.... thanks again for such kind words

[@42bergy]

Hi Zdenka, your seaside intro for this video is stunning: a really moody symphony in purple and blue! I love the Viltrox Speedbooster and think, the gain of the merely original focal length and aperture of the EF-Lenses is worth the compromise of the slightly smooth edges in the pictures.

[@ZdenkaDarula]

It is worth it... especially if you have the lenses already why not use them. You would be surprised but it is only a lake.... Lake Ontario but it does look like a sea especially during sunrise. It was really nice morning...

[@kenbest7660]

You're getting better all the time at this vlogging stuff. Kudos on all the effort you are putting into this. Making you a better videographer. Good review. Of course though, as some have pointed out the size difference was somewhat off.

[@ZdenkaDarula]

Thank you for your kind words. Yeap I totally didn't realize it until later. The numbers really got me... I was looking at the numbers the camera shows and totally forgot about the cropped sensor. Oh well... visual part was the most important and I left message with explanation so hopefully lots of people realized it. Let me put it this way.... I am soooooo ready for the school to start. I need my quiet time to concentrate again 😀😀😀

[@raywu6787]

Thank you for a detailed comparison. From them, I can see that using SpeedBooster brings additional color differences. Therefore, if you use SpeedBooster, it is best to use a directivity white balance filter DCC40 to correct the color difference both of the camera white balance and the dual lens.

[@ZdenkaDarula]

[@grat2010]

Outside of landscapes (which I don't do a lot of), corner sharpness is never anything I'm concerned with as my subjects are rarely found there. Also corner softness is a non-issue if I'm going for nice bokeh anyway. Both adapters are great if you have an M50, just have to be aware there's a limit to what the speedbooster can accomplish. Don't buy it and expect it to make the M50 full frame. Edit: Ahoj Z!

[@ZdenkaDarula]

Totally agreed.Great comment. Have a great day!

[@DanaEpp]

I think the original question about the vignetting may actually be something completely different. I’ve noticed if I use a lens designed for a cropped camera (like my Sigma 30mm f/1.4) the speed booster will show a physical vignette. For that lens I have to use a normal adapter on my M50... which also means I lose out on the extra stop and 0.71 which I was wanting to make 4K livable. So it’s good to own both adapters, depending on your arsenal of lenses. So my nifty 50 on the speed booster ends up being pretty close to my sigma on a raw adapter... but is WAY lighter.

[@ZdenkaDarula]

Thanks so much for this helpful comment. Thann you for sharing 🌞📷📱

[@acarrasco]

Zdenka, thanks for the comparison. I am not absolutely sure but ... an EF lens in the M50, lets say a 50 mm, works not as a 50 mm but like an 85 mm,so with the speedbooster it is to that focal length that you apply the reduction. Congratulations on your growing channel.

[@ZdenkaDarula]

Yes that is right.... sorry if there was mistake in the video. I have to double check when I get home. Either way if you download the photos correct number is in the photos recorded with camera.

[@jhudyejhudye4836]

Thanks for this video. I have both speedbooster and just an adaptor... I use them both they very useful depend to the shots ur getting.

[@ZdenkaDarula]

You are very welcome

[@Aviator168]

My take is if you want sharpness, just buy the lenses designed for the particular lens mount. The lenses designed for bigger physical pixel sizes might be softer on the smaller counterpart cameras.

[@ZdenkaDarula]

Yes, if you have the budget that it will be the right to take

[@snuwan]

I have both. light which goes through the booster has to go through more glass and that glass enlarge the picture as I read. So obviously it will be softer. I would not use this for photography much. But for video shooting a little softer image would not make a huge difference. so my use of the speed booster is primarily for video. I get more light, wider angle and lower aperture. Only flip side is that you can not use EF-S lenses with it.

[@ZdenkaDarula]

Zdenka, does the Viltrox Speedbooster preserve the autofocus feature when using certain lenses with the M50, or does adding the Speedbooster mean that autofocus lenses lose the autofocus function?

Hi Zdenka, thanks for sharing and taking the time to produce a great review of the Viltrox speed booster picture quality - interesting. I have the standard Viltrox adapter and I am very pleased with this as it increases the number and type of lens I can use - always a bonus! Looking at the image files you kindly provided, the speed booster does slightly soften the image which helps certain shots tremendously if you want to create a softer feel. Personally though I do prefer my images to be nice and sharp, as I can always soften then if editing, but that's just me!!! As I am a beginner in leisure photography, getting things sharp is one of the challenges, as is experimenting with the other things the M50 can do. It's all good fun and a pleasant learning curve - helped by very interesting and useful videos like yours. Thanks and enjoy.

[@ZdenkaDarula]

Thank you Mark for your view on it. It is sometimes struggle even for experienced photographers especially when you are in very hard light conditions.. I understand your view on it absolutely. I use Viltrox mainly for video. Have a fantastic day! 📷🤗📽

Hello! We were just commenting about the release of the new Canon camera's just yesterday and today they announced them. I have not pre-ordered because I am still not sure if I want mirrorless or dslr. I want to see a little more about image quality. I think the price for the 90D is a little high if you get it in a bundle. I can get a full frame 6D mii or full frame mirrorless r mount for the price they are asking for a cropped sensor camera. I also see Sony released 2 new cameras also! They planned that perfectly! Lol! Curious to know your thoughts on the one or both of the Canon offerings. Have a great day!

[@ZdenkaDarula]

Thank you for pointing this out. I just read some articles and I like the mirrorless.... 120p at 1080... yes please... this will be a interesting video to make.. thanks so much for sharing it!!!

[@drutgat2]

Thanks for this, Zdenka, and for uploading the photos so that we can download them and compare the relative merits of the adapter and the speedbooster. In effect, the speedbooster, does also provide a different focal length (it actually makes a wider angle lens of any lens that you are using, despite the crop factor of mirrorless cameras, such as the Canon M50). So, it is not really an either/or choice in terms of focal length. There are other third party speedboosters, in addition to the Viltrox. For example, the Andoer EF-E II Lens Mount Auto Focus Reducer Speed Booster Adapter for Canon EF Lens to Sony E-Mount Camera.

[@ZdenkaDarula]

Yes thank you.... I know of them...I am sure other people might find this helpful. Thank you for contributing....🤗📽📷

I adjusted the sharpness my Viltrox by putting my lens to f8 then turning a quarter or half a turn at a time clockwise until it was the sharpest i could get it. (Involves taking lens on and off multiple times on a tripod and take multiple shots to compare) ..simple

I'm curious about why the comparison between a full frame sensor and an APS-C. Although the crop factor would mean different images, I think a 100% of an 80D and a 100% of the m50 (given the similar sensors) is a more valid comparison.

[@ZdenkaDarula]

[@billy9506]

With regards to the adjusted focal lengths: As the M50 is a 1.6x crop that should be taken into account first, no? So the 5d at 200mm is equivalent to M50 at 227mm (hence why it's zoomed it a bit more). [Edit] just read other comments/replies addressing this.

Very informative but one thing you missed ie. adapter accepts all EF and EFS lenses ie. adapter accepts all full frame and crop sensor lenses but speed booster only accepts full frame lenses so there is a big limitation with speedbooster as there more crop sensor lenses than full frame lenses. Do you suggest manipulating crop sensor lenses to fit with speed booster?

[@ZdenkaDarula]

Thank you... yes I am aware .. I don't suggest manipulating... just get proper lenses..

[@okaro6595]

That limitation is not an oversight. It is how the speed booster works. It cannot work on an APS-C lens. There is nothing to boost, the sensor already uses the whole image circle. There are far more full frame lenses. There ha been 152 EF lenses and 24 EF-S lenses. This includes different versions.

[@yudaadhiguna4577]

Do you know why the speed booster has that attached little stand instead of looking like a regular lens? I just wonder if that little stand would interfere with stabilizers.

The thing I wonder about is whether the more expensive Metabones speed booster has the same result in the corners? This video suggests the corner softness is a speed booster issue, but what if it is a Viltrox issue? It is possible that Metabones is just making a huge profit while producing the identical product. But it is also possible that the extra costs are due to better glass, better manufacturing processes, and better research and design processes. I do not know the answer to this, but I have a suspicion that the Metabones speed booster would produce a better result.

[@ZdenkaDarula]

Very interesting comment... thank you. Truthfully I don't even know the product you are talking about so I am going to research it and possibly ask them if they would be interest in review... thanks for pointing it out

[@artistjoh]

Zdenka Darula great if you could make the same comparison using the more expensive speed booster vs the Viltrox vs Full Frame. I would also suggest including a plain adapter without glass. The reason I suggest this is that a lens designed for full frame normally performs less well on an APS-C sensor. On the Metabones website they state that the Metabones speed booster has improved MTF but in fine print below they qualify this as “compared to adapter without glass. They are trying to imply that MTF is improved over the full frame result, but in fact they are only talking about adapted lenses. Your testing regime is perfect for the Viltrox. It would be even more valuable to include the other possible options. I agree with you, that even with a poorer result, the advantages outweigh relatively small problems. It is why I think that people who won’t use filters in fear that they lose sharpness are foolish - it is in fact a matter of weighing the relative merits of advantages vs disadvantages and the filter wins in most cases in my (and most photographers/videographers) opinion. Focal reducers (“speed booster” is just the marketing name that Metabones introduced to sell more focal reducers) are brilliant - just like teleconverters, they give us more options and are one more reason to love mirrorless cameras.

thank you for your comments and thoughts... Yes it is personal preferance... that is why I said that in the video to let everyone decide on their own... :)

Hello, my real estate set up is a Canon M50 w/ the Laowa 9mm f2.8 ef-m mount lens. Which equates to a 13.5mm full frame. Is there a Viltrox speed booster or anything that will allow me to get better/wider 4k and allow more light in? I run into some houses with very poor natural light.

Hello beautiful lady. You have the best videos. I've learned so much. Thank you...

[@charleswendt4868]

I have both, Hope you are doing well.

[@ZdenkaDarula]

Thank you... yes I am all right... wishing you great day 😊📽📷📱📹

[@sandeeprajthemotivationals4578]

Thanks for this useful video. Suggest me a lens to shoot videos while I teach and write on whiteboard with marker ?

[@ZdenkaDarula]

It all depends if you want the camera close to you or far away... if close then regular kit lens is fine. If far away you need telephoto ... best of luck.

[@redvulps]

I use both, and I like quality from both and for the final result, unless the person start doing some pixel peeping, I guess the difference won't be noticeable. What I can say is, with my 50mm 1.8, depending on the subject(mainly moving ones) the focus get less precise when using 1.2 but that's normal considering the the usage of an adapter(imo of course), the only case that I can say that the focus was terrible is when I used Sigma 24mm 1.4 with the speed booster, this one the focus missed almost every time, even at 1.4, but I wasn't able to do any in depth tests and I might be doing something wrong with my settings anyway.

Hi... does this viltrox speedbooster wiggle a little.... i heard this complaint from many people on the internet..

[@ZdenkaDarula]

I don’t feel it wiggles for me…, so far no issues… last 2 years I have it

[@piyushkumar6456]

Thanks again! Great Video.

[@ZdenkaDarula]

You are very welcome

[@lizatko3.]

Zdravím Zdenko, chtěl bych se zeptat na váš názor, zda je lepší koupě speedboosteru s 50mm f/1.8 nebo obdobný objektiv určený pro m50 (například 22mm f/2.0)

[@ZdenkaDarula]

Zdravim nazpet. Obe moznosti jsou dobre. Pokud mate dalsi EF objektivy tak se vyplati koupit speedbooster pokud ne slysela jsem ze 22m objektiv je vhborny

[@lizatko3.]

@@ZdenkaDarula No nemám zatím vůbec nic až na kitový objektiv, ale mám v plánu více natáčet a fotit, takže určitě budu kolekci objektivů rozšiřovat. Děkuju za odpověď a určitě pokračujte v tvorbě takovýchto videí. 😉

[@easyyummyhealthy]

Zdenka i love colors of this video, maybe because of soft sky light or maybe its because of your beauty :P but which camera did u use and is there any color grading?

[@ZdenkaDarula]

Thank you for the compliments . ... I film with Canon M50 and yes always colorgrade my videos.. 📷📽📱📹😊

[@easyyummyhealthy]

Haha your welcome, no compliments there :) nice color grading then and maybe sky is looking so beautiful because of polarising or nd filter

[@ncuhJP]

Hello there. Does it work with any EF lenses or not? I found a list of lenses on viltrox's site and there are many lenses without supporting by this adapter. Or mb I'm stupid?

[@ZdenkaDarula]

:)):):) the lenses I have (Canon EF lenses) are all working great with speedbooster... I am not sure about other brands unfortunately

[@frkfir]

Hi, how does the VILTROX EF-EOS M2 speed booster affect the depth of field when you shoot photos with the AV mode and with the EF-M 18-150mm lens?

[@ZdenkaDarula]

I am sorry I don’t have such a lens so I cannot really answer that

[@frkfir]

​@@ZdenkaDarula My question doesn't necessarily refer to this lens but to every lens. Also, If I'm looking to shoot photos with good quality of depth of field, what lens do you recommend that beats to my EOS M50?

[@herbertcampos8377]

Hello Zdenka, you know I did a test with the 24 105mm F4L, the same you have, but I did it only using M50, with Commlite adapter and speedbooster and in my opinion, and I am not sure why but, the pictures were sharper with the SpeedBooster than the Commlite, very strange, I was expecting the opposite...

[@ZdenkaDarula]

That is interesting... it also depends lots on camera, lens, if you didn't move and so on... I know the last shot I was showing could be a lot sharper.. j thinn I moved little.... but yes results are always different. I'll compare the adapter too... i would like to see ....📱📽 thanks for pointing it out

[@charleswendt4868]

I also have Commlite Boosters and Adapters for my Olympus and Sony cameras

[@ZdenkaDarula]

Very interesting.... thank you for sharing 🤗📱📷📽📹

[@mohzinabdulmuneer4966]

Does the speed boosters damage the focus mechanism on a long term use?

[@ZdenkaDarula]

That’s something I cannot answer but I don’t think so otherwise they wouldn’t be selling it

[@neilyakuza6595]

Would in camera Sharpening help the softness?

[@ZdenkaDarula]

Not really

[@MsSatria18]

Hi, Thanks for sharing. Learn a lot from your channel. Can you please help me out a little bit, recently I was thinking of getting a new lens. I'm using the m50 with the speed booster but was thinking to get a afs lens. The camera shop told me the speed booster only suitable for af lens, is it possible if I use a extension tube infront the speed booster to fit the afs lens. How's the quality if it's possible?

[@ZdenkaDarula]

Yes it is only compatible with EF lenses.

[@jmrvisualstw]

APSC crop factor multiplied by the 0.71 (1.6x0.71=1.136) multiply it by the lens focal length and the aperture. ex; 50mm multply by 1.136 is equals 56.8mm equivalent on a fullframe not 35mm as you said, also the 70mm is not going to be a 49mm focal length...as you can see on your sample images the M50 with the viltrox adapter are more compressed than with the fullframe 5d4.

[@ZdenkaDarula]

Thank you for sharing your thoughts 😊🎥🎬📸

[@buddah610]

Surprisingly, I found the colors more pleasing on the M50 but definitely softer However, not by much. I have commented before that I had the M50 when it first came out but since I only shoot stills, I just found it slightly underwhelming of I needed a pro level shot. But,the more I watch your channel, I keep thinking about getting the M50 again but using the speed booster and adapter. I am waiting to see what Canon does as I am sure you have heard the rumors about the M6 m2. I still need a viewfinder and I don't think that has one. I need a camera desperately! My poor Nikon is holding on for dear life! I picked up a D3300 after my T3i died. That's how long it's been! I just bought a new phone and never thought I would be using it as a go to but the photo's are fantastic. I still need a dslr or mirrorless but in the meantime, this might have to do. Have a great day!

[@ZdenkaDarula]

I totally agree with you. Just wait for the next camera. I am waiting as well. As for the viewfinder try to get used to screen. I don't know your age but the eye issue I have and many other photographers I spoke to is from using and straining one eye... if I knew it earlier I would have pushed myself to use the screen....but wait for the new camera for sure

[@buddah610]

@@ZdenkaDarula I am 53 and I do have an issue already with my left eye. I try to use the screen and using my new phone is helping. I still can't believe the sharpness and clarity! Thanks for the advice. I am going to wait for the new Canon. I hope its soon because fall is coming and I need my beautiful Fall colors! Take care!

[@ZdenkaDarula]

@@buddah610 yes that is right. Hopefully it arrives soon. I am very curious as well. Personally I like colors from M50 better as well absolutely

[@gilpineda]

does it really drain the battery even when not in use? says if u leave the lens on it will drain the batter overnight even if the camera is turned off

[@ZdenkaDarula]

Yes it does but I just did firmware upgrade which apparently took care of it. So far I haven't had a chance to test it

[@jdrodriguezmera]

Thanks for your video!! Do you know if it's possible to use with speedbooster the tokina 11-16mm with canon m50??

[@DAVIDMARTINEZ-ez6sp]

Hi Zdenka! Thanks for such a helpful video! I have only one question: Is the speedbooster compatible with EF-S lens series?

[@ZdenkaDarula]

No unfortunately... it is compatible with EF lenses....

[@DAVIDMARTINEZ-ez6sp]

@@ZdenkaDarula Thanks so much! I'll have to buy the adaptor... 😔

[@parranoic]

The quality of the adapter or of the image is really not the issue. What bugs me is the focusing speed which compared to even the cheapest Meike ef to ef-m adapter is slow. Now I also have a Sony A7ii with a Viltrox EF-NEX 4, same story here, focuses reliably but it's slow...

[@ZdenkaDarula]

Unfortunately once you add extra components this will always happen 📹📽📷📱

[@sounakbanerjeetubai]

There's a common complaint about the speed booster going around on the internet. It seems to cause battery issues if you keep it connected to a camera overnight it completely drain the battery. Just wanted to ask whether that is a general issue or is it a manufacturing defect in some of the samples (whether you faced the same problem). Also in case that is a general issue, is the adapter also affected? And finally, are there any noticeable differences between the Viltrox adapter and the expensive Canon adapter?

[@ZdenkaDarula]

I think it was an issue from the past. The new version doesn't do it... they mentioned that updating the firmware helps... 📽📷📱

[@sounakbanerjeetubai]

@@ZdenkaDarula thank you very much!

[@georgekapaniaris7216]

Noooooo on an aps-c sensor a 50mm lens will be 50x1.6x0.71=56.8mm. The main problem is not only the softness which it introduces in the corners at low f-stop numbers (unlike the numbers in your test which were mostly f8) but also the chromatic aberration is severe...

[@cowboy6591]

I don't understand the scuttle-butt out on the net about this. For me it's a simple choice, I like paranormal investigations and that requires going through abandoned old places with no utilities [light] at night and when I am faced with the choice 1, SUPER SHARP or 2, BRIGHTER NIGHT SHOTS LESS SHARP It's a simple choice what good is a perfectly sharp in focus picture if it is under-exposed and nearly a blacked out image. The speed booster captures more light at the cost of another piece of glass to add to the refractory factor. It's not a hard choice, that's especially true if you have BOTH speed booster and Adapter. Ya the EF 50mm f/1.8 is a great lens for lower light and needs the adapter to work. And it does not have that extra piece of glass. But the speed booster images seem to let more light in so they still come out brighter. The conclusion is when I absolutely have to have more light and the ef 550mm f/1.8 wont do, then I whip out the speed booster and sacrifice a tiny bit of res for a properly exposed shot. No brainier, be prepared with both Speed boost AND adapter. The adapter is cheap, no need to squabble over 50 bucks. I started using an old fashioned light meter again to judge that fine line between speed boost or adapter for my ghost hunting.

[@ZdenkaDarula]

Thank you very much for writing this long comment and share your thoughts. Have a great day

[@SachinBalan_PB]

Oh! I was waiting for this video. Yo that's 56mm lens. Please tell viltrox to add there adapter in Amazon.in for Indian market. I'm missing it so much. But we all know to get things done right we all need a good photo editing monitor with 100% AdobeRGB or 99% ProPhotoRGB for professional post-processing the RAW image file and a monitor colour calibration device like x-rite Colormunki Photo. Madam what do you thinking and recommend about it.

[@ZdenkaDarula]

Thank you for your comment. Yes I noticed it is not in Indian Amazon... I was surpised too.

[@MSGRetired]

So I watched a few more video's and started looking for a used 70-200 lens. I will use it on my 50D and the M50 with Viltrox Speed Booster. There seems to be a lot of them available but what specific model should I look for? You say yours is 12 years old or more.. Thanks for all the Great Video's.

[@ZdenkaDarula]

When you buy something like that it holds value and you can always sell it for lots ... I would make sure it has Image Stabilization. Mine is F/2.8 I think... great lens.

[@georgantonischki1188]

Hello Zdenka, I bought the speedbooster on your recommendation. I really like it with M50 and 50mm, 85mm and 100mm prime. I think it is usable for many shots. For Architecture it is critical, as there seems to be more distortion and the colors are also different (also observed in your comparison) and I am lazy in post. I used the booster also with my Lensbaby, but here the vignetting makes using the baby less fun. I have a cheapo Ukrainian replacement which I like better anyhow. The Tamron Fisheye Zoom was a disaster. CA is visible in the thumbnail... thanks for your fun and great content! Do you have something on candid portrait shooting? How do you do this with wedding guests?

[@ZdenkaDarula]

Thann you for sharing your experience... greatly appreciated.. 🌞 as far as candid style goes, yes I will make videos on that in the future for sure. Yes during weddings that is the way I always shoot. Cheers 📽📷📱
