Just got the set up today. However the ISO is 2.0, not 1.8. Can’t say I’m disappointed till I try it.

[@j_stories2225]

I wasn't disappointed I'm good with a decent lens

[@BenjaminMcClain]

Hi, I just set it up today. Using the metabones bmpcc4k ultra to Nikon speedbooster. Works beautifully and while the manual aperture is a little tough to get used to by using the adapter instead of the lens (The lens is fully electronic/auto aperture) once I got it set up it is working perfectly.

[@LilianaSaeb]

Nice! I have this setup (Panasonic G85 + Sigma 17-50 mm + Viltrox Speedbooster) and I'm super happy with it, I have a couple of videos with it on my channel. Glad to see someone talking about it more in depth. I think this is one of the best setups for the price.

[@GustavoMendozaCanales]

Hi Nolan, I just found your channel in my recommendations feed and it's nice to see someone using exactly the same equipment as I, so I feel approached 😃 Since the stabilization on the lens doesn't work (even on a Canon body it didn't work fine at all), what I do is turn on the electronic stabilization on the G85. I have never noticed any kind of weird distortions or strange artefacts. With both ibis and electronic stabilization, at 60 fps and later using Premiere's warp stabilizer, the result is more than satisfactory. You just got a new subscriber!

[@NolanGunn]

That's awesome Gustavo! And thanks for following along! It really is a great setup for a lot of different situations. Good luck with it!

[@smashtime1904]

I actually just got this combo - I went on eBay for about a week bidding on used ones in 'Like New' condition with my max bid set to $210 and got one for $225. Pretty stoked. I've been emailing Viltrox about official support - this lens is great for adaptation as it can be used on Panasonic as an affordable alternative to the 12-35mm f2.8 where you exchange IS for an f2 exposure wise that acts like a full frame f2.8 if I'm not mistaken in terms of DOF(or an f4 either way it's better than f5.6) Fuji or Sony apsc or full frame super35 mode which is awesome. The OOF area is super creamy and used in conjunction with the Panasonic x5 ibis(I have a GX85) it's outstanding. Even without the lens support back button focus works reasonably well - you should try it out if you haven't. Have you made any considerations on a 70-200mm f2.8 yet? There's the obvious Sigma 50-150mm f2.8 HSM or OS, the newer Sigma 50-100mm f2, the outlier Tokina 50-135mm f2.8, a native 35-100 or 40-150 2.8, or you could go old school with a Konica 35-100mm f2.8(I've been looking at others like a Tamron 35-90mm f4 non variable aperture as well).

[@NolanGunn]

Hey Sam! So my next will most likely be a Mft wide angle prime. Thinking of the sigma 16 1.4 hopefully! Still Loving my sigma 17-50 setup tho!

[@jayclas4023]

Nolan Gunn I have the 16mm 1.4, I’d go for a 24 or 35mm 1.8 because they are cheaper and you’d only use them to get better low light if you really need it. Other then needing better low light, the Sigma 17-50 with color a lot at 2.0 with the speed booster.

[@NolanGunn]

I ended up getting the sigma 30 and 16 1.4! 👌

[@jayclas4023]

Nolan Gunn perfect! That’s perfect! I meant a 28 or 35mm at 1.8 because with a speed booster you’d get f1.2 but the 30mm 1.4 is just as good🤗

[@TheHouseLime]

Using this lens on a Canon 77D. The autofocus gets a bit noisy and hunts a bit but it's a huge step up from kit lens. Can't go wrong for the money!

[@NolanGunn]

For the money definitely not!

[@ecaIos]

Yooo I have this exact lens with the efm2 speedbooster 🤣🤣 there really aren’t much fast zoom lenses that are cheap, picked mine up for $100 because of an “issue” with focusing but haven’t really noticed it, awesome pickup 😃😃

[@NolanGunn]

$100? Wow that's awesome! Good find 👍🏼

[@The_Other_Dan]

I had this lens for my Canon 550D. I was so stoked when I found out that I could continue to use it on my new G95 with a speedbooster!

[@NolanGunn]

That's awesome!!

[@glsracer]

How does the photo auto focus work? I have this lens and have also been using it on a 550D but I'm looking at the G9 and wondered if it would work ok.

[@justesmond]

I already have this lens that I've used with my photo cameras for years. I was looking to get the 18-35 based on all the hype of other creators. I'm glad to see this review to confirm that this lens should work great with the BMPCC 4k. Now I don't have to immediately run out to get the 18-35.

[@NolanGunn]

Yes! Will you be using a speedbooster?

[@justesmond]

@@NolanGunn Yes. I plan to. I’m looking at the Viltrox speed booster. I’ve seen a few comparison videos. While I do see maybe a slight (5%) sharpness difference I don’t see the either of the Metabones speedboosters being 3x or 5x better than the Viltrox as their price suggests.

[@NolanGunn]

Agreed. The Viltrox EF-m2ii is amazing for the price, it does flare a bit if you backlight outdoors with harsh light or indoor with windows so just be aware of that.

[@xxxag1768]

Mines coming in tomorrow! Was able to scoop one for 160 👌

Dang! That's amazing!

[@johnpatrickbishop]

Interesting thanks... about to bite the billet on a speed booster I think good to see other options compared to the 18-35. I assume you bought in canon mount?

[@NolanGunn]

Yessir! Canon mount. It's been working great for me!

[@dmtalending3533]

Great video! I have a gx85 and am considering this combo too. What about sigma 17-70 f2.8-4? Did you consider this lens before? I found one post say that 17-70 can get f2 at 70mm on EM5 with virtox speedbooster. So I’m struggling to make a decision between 17-50 and 17-70.

[@NolanGunn]

Biggest difference is a fixes aperture and variable. I really need the fixed aperture for video. But if you don't, it's a great option!

[@danyalvisuals]

Great video

[@NolanGunn]

Thanks Danyal!

[@adrienpayet]

Can't wait to see the sample footage! What about the sharpness? I have a g7 with viltrox speedbooster and 50mm 1.8 for now, I'm always relying on my friends EF lenses 😂

It's really sharp! I'm going to run some sharpness tests at some point, but just to my eye it looks really nice 👌

[@adrienpayet]

@@NolanGunn Great ! Thanks for the answer !

[@NolanGunn]

@@adrienpayet No problem Adrien!

Can you use the touch focus in manual mode with sigma 17-50 2.8? I would like to know. I don't use autofocus, but just point the focus touching the LCD in M mode is awesome and pretty handy using panasonic native lens.

[@NolanGunn]

If I'm honest, I'm not 100% sure. I know it's possible with an active adapter, but not sure if it works when you're on manual focus.

[@kimeriksson7445]

Hey man, have watched enough to know that you really know your stuff, figured you're the one to ask: Trying to use this lens with the Viltrox ef-m2 II on my Blackmagic 4k... Ouff, can't get neither the Aperture to show nor the image stabilizer to work... Any ideas? I don't get the viltrox to clearly click/lock on to the sigma lens, only multiple small "clicks" while turning it, and I just kind of turn it until it feels firmly in place. Have all the newest firmwares also.

[@NolanGunn]

Hey! I really appreciate those words. One thing about the viltrox that's really weird is if you hit the little side lever (it's a little black tab on the side of the adapter that goes up and down) it disables the ability to use the aperture on the camera. The only way I've found to reset it is to turn the camera off and back on. If that's not it I would start by trying other lenses on the viltrox and see if they work. Try to isolate the lens or the adapter as the issue first. See if you can find a canon rebel body you can test the 17-50 on and make sure it works. If it does, then you know either the adapter or camera are faulty. Sorry i can't be of more help! Keep me posted.

[@bornindalmatia]

Hi there, great video above all. :) What do you think compared to the Tamron 17-50mm 2.8?

[@NolanGunn]

Thanks so much! I'm really not sure about that lens, but it is very similar from what I've seen.

[@bornindalmatia]

I've been looking at some comparisons where it turns out that Sigma is sharper and Tamron has better stabilization. I just cared how Tamron would work with the adapter.

[@colinire15]

Great video. How successful did you find the stabilisation was in this combination with the Viltrox?

[@NolanGunn]

Everything worked as it should! I did notice that the stabilization would only turn on once you start recording though.

[@colinire15]

Thanks fro the reply Nolan. I think I could easily deal with that.

[@YamilIsaac]

I'm torn between buying the viltrox speedbooster or a plain K&F adapter from Nikon to MFT . I understand the difference is getting 12-36mm f2.0 or 17-50mm f2.8... What does everyone think? Is there any other difference on the vignetting or anything else? THANKS!

[@NolanGunn]

The F/2 is pretty nice to have when it is focal reduced. But having a longer reach at a 35-100 is pretty nice as well.

[@rafaelvanleeuwen]

Great video! Just curious, what would you choose? Sigma 17-50 with the Viltrox EF-M2 or just a Lumix 12-60 mm (for filmmaking)? And how about the stabilization of the Sigma 17-50 in combination with the Viltrox?

[@NolanGunn]

Definitely 17-50! You would have a consistently bright aperture and nice depth of field. The only drawback would be the 17-50 is a good bit heavier. But that's what I would go with!

[@rafaelvanleeuwen]

Nolan Gunn Thanks! I have ordered it, very excited to use it :)

[@NolanGunn]

@@rafaelvanleeuwen let me know if you have any questions once you get it!

[@NickGeorge]

dude looking back at all this would you rather get a speed booster for the g85 and buy full frame lenses or upgrade to a full frame body camera?

[@NolanGunn]

At this point, I think full frame is the future. The GH6 will effect my decision quite a bit. If the GH6 has amazing lowlight and autofocus I would consider sticking with mft. But at this point I would like to see a Sony A74 with some a7siii features. The Panasonic S1 has a lot of flaws that are hard to sell me on. Short answer: depends on the GH6, but right now I would go full frame body.

[@KMLR2012]

So the lens IS works with the Viltrox ef and the Sigma 17-50 mm combo? I'm thinking about buying this combo. Trying to decide between this and the Panasonic 12-35 mm . To be used on the original BMPCC.

[@NolanGunn]

Yes, it works! It's not as good as the G85's Ibis, but it takes the edge off of my GH4. Note though that they both do NOT work together. You have to choose lens OR body stabilization. I guess it depends what you want for a lens. The 12-35 is weather sealed and smaller. You will get a little better depth of field with the viltrox and sigma. The 12-35 is definitely sharper from the comparisons I've seen AND it has the dual IS capabilities for ridiculously smooth video. What are you shooting?

[@olivier6681]

Great video 😀 i have g85 and gx85 with viltrox ef..with canon 85mm 1.8...perfect for portait..Sigma 17 50 no problem for aperture, autofocus and stabilise lens work with g85 dual is ??? Thxx men

[@NolanGunn]

So you can't have both in body and lens stabilization on at the same time. Because the software isnt compatible, they fight with each other. So you have to pick one or the other. Thanks!

@@NeroMCdefinitely in body!

[@GeraldBertramPhotography]

Very interesting video! I had considered using this lens on my M 4/3 camera with a speed booster but I had thought because the Sigma 18-50 is for APSC sensors that if I put that on a speed booster I would have vignetting at the wider focal lengths on my M 4/3 camera. Is that not the case?

[@NolanGunn]

Depends on the speedbooster. My .71 viltrox doesn't have any vignetting at all, it may be different with the .64 version. Good point though!

[@GeraldBertramPhotography]

@@NolanGunn I assume you have the Viltrox EF-M2? This is great news! I already have the lens so I might just have to get that speed booster now!

[@NolanGunn]

Yessir! It's been working out great for me! 👍🏼

[@StudioGalvan]

Hello All, I also own a Nikon D5300 (and as per Nolan's video and exp with other lenses), I was wondering how the fine focus performed. I'm going to want to print large so pinpoint focus (Esp at 2.8 or 4) is going to be critical.

[@NolanGunn]

Definitely not the best for fine focusing. The throw is only 1/4ish of a turn so its hard to be precise. But at f/4 you could easily nail focus, you would just have to use a focus assist if your Nikon has one. 👍🏼

[@StudioGalvan]

Thanks@@NolanGunn

[@sdhute]

Are you using alot of canon glass on your MFT? Have you tried the panasonic 42.5 or olympus 45mm ?

Hi. Just got my hands on these lens, using G85 with it. Question: Do u use in body stabilisation with lens OS on? or should lens OS be off when using g85 IBIS. It might be me or something but Ive noticed like image is more shaky with lens OS on... or Im doing something wrong...

[@NolanGunn]

When I tested it, the best solution was turning lens stabilization off and IBIS on. I got the best results that way 👍🏼

[@Myosh03]

@@NolanGunn Ive tested it few times and it seems that in AF mode it needs a second to utilise both image stabilisation while you focusing, funny. On manual focus it works great, there's only a bit of advantage using OS on these lense tho.

In video as you said it isn't an issue, but you will get a vignette in photo sometimes. You could try turning off the IBIS so the corner vignettes don't move too much and then apply a reverse vignette in post. Not sure if that would help, but worth a shot!

Thanks! No problems there. Aperture works great both on the lens and in the adapter. Whichever you prefer.

brilliant. i must have a broken viltrox!

[@NolanGunn]

Before you assume that, if you use the viltrox's aperture switch, it disables the cameras until you restart. So just in case you can't adjust it, try restarting your camera. If that doesn't work, I would reach out to viltrox. Hope this helps!

so can you please suggest me a lens similar to sigma 17-50mm which supports in viltrox speed booster for m50... please reply

[@glsracer]

@@ajithjohny4345, so the 17-50 f/2.8 will work natively on the M50 if you have Canon's EF to EF-M adapter but will not run at f/2.0. If you want to use a focal reducing adapter with the M50 then you will need to look at a full frame lens like the Sigma 24-70 f/2.8. They can be had for around 500 to 600 USD used IIRC. In either case you must use a full frame lens in order to use a focal reducer with an APS-C sized sensor like what is in the Canon M50. The m43 sensor in the Panasonic cameras is smaller than APS-C which is why it can use a focal reducer with EF-S glass.

[@tonaiyadyer3558]

I want to buy thiz lens

[@thomasgagel]

Great video and I agree with basically all of that, but when calculating the 35mm equivalent it would be f2.8 (iris aperture) , ☓. 71 (viltrox) ☓ 2 (m4/3 crop factor) = 3.9, not 2. (35mm equivalent). Am I wrong? Someone help me!! Great video though.

[@NolanGunn]

Right. So the exposure would still be an F2 but the equivalent in depth of field between a full frame would be 3.9 like you said. As far as understand exposure values are the same between mft and ff at the same aperture... Don't quote me though!

[@thomasgagel]

OK thank you though because I was really unsure there for a second. Thank you for replying. You have great content.

[@filmmakerssng8800]

best lens me favorite

[@NolanGunn]

That's awesome!

[@phaselead_dj]

Thank you for your review, but I'm a bit confused. At first I thought, since the speedbooster is made for EF lenses, not for EF-S lenses, using sigma 18-35 or 17-50 you reviewed may cause vignetting or even worse outer parts of the sensor may become just black. But, it seems to work so great. Is it because the speedbooster does not boost (or concentrate lights) so much? If there's a x0.5 speedbooster, will it cause the problem for EF-S lens?

[@NolanGunn]

So essentially, Canon owns the patent for the EF-S mount and only uses that for their native apsc lenses, as you know. Other manufacturers (like sigma) from what I understand, use the EF mount for their full frame AND apsc lenses because Canon is the only one who uses EFS. So even though the 18-35 and 17-50 are both apsc lenses, they have an EF mount. In regards to vignette, in video it doesn't have any vignetting on my G85 or GH4 with the .71 speedbooster at 17mm. If you switch to photo, you WILL see a vignette (very small corner blackness) because of the full sensor 4:3 aspect ratio in photo mode. The video 16:9 effectively cuts off any vignetting. I would imagine the .64 speedbooster would run into some video vignetting issues though. Let me know if that makes sense and if you have any questions!

@@NolanGunn Thank you so much for explanation!! So detailed and really helped me understand. Btw, I watched your works and they are so great. Thank you for sharing your nice setup and footage :)

[@NolanGunn]

I really appreciate that! Just trying to get better 😊

[@SuperChonny123]

which speedbooster did you use?

[@NolanGunn]

Viltrox efm2 mk1- I would recommend getting the newer one now.

[@wwijma2000]

what viltrox speed booster did you use?

[@NolanGunn]

For this video, Viltrox EF-m2 (version one). I recently bought the Mark ii version and it's a bit sharper and close to the metabones according to Gerald Undone

[@danielaudacious]

Good Job kid.

[@NolanGunn]

[@NickGeorge]

just so you know I can't buy the LUTs because PayPal is the only option and the PayPal window doesn't work when I try to log in.

[@NolanGunn]

Interesting! I'll check into that. Thanks!

[@NolanGunn]

Just added credit card checkout! I didn't realize it didn't accept those.

[@isart3757]

compare with 18-35 ?? who is more bokhe ??

[@NolanGunn]

The 18-35 would have more. I could do a comparison at some point!

[@olivier6681]

Hello for photo, no problem vignette?

[@NolanGunn]

Actually for photo there is a vignette when shooting the full sensor 4:3 aspect ratio. The 16:9 video cuts it out. So, yes. It has a vignette in photos.

[@olivier6681]

Nolan Gunn thxxx

[@NolanGunn]

Absolutely!

[@JeromeAnthonyStudio]

How about the AF motor? Is it noisy?

[@NolanGunn]

You can hear it slightly, but I shoot manual focus anyways so it's not an issue.

[@JeromeAnthonyStudio]

@@NolanGunn thanks man..👍🏼

[@NolanGunn]

@@JeromeAnthonyStudio absolutely 👌🏼

[@relationshiprundown-thelov5094]

The 17-50mm 2.8 is definitely better for video than the 18-35mm. The 18-35mm is sharper and great for photography but the image looks too clinical for video without using a filter. Plus the Image Stabilization on the 17-50mm is a plus for people with active lens mounts.

[@NolanGunn]

Yeah not a whole lot of character for sure. I feel like owning both would be ideal!

[@sriharibr3151]

@@NolanGunn For my canon 77d(APSC), Sigma 17-50 and sigma 18-35....which is better lens for people photography, weddings, travel, portraits, events(mainly indoor)......not a professional but an enthusiast.....

[@NolanGunn]

That’s awesome!

[@sriharibr3151]

​@@NolanGunn which one should I choose ? 17-50 or 18-35?

[@NolanGunn]

18-35 if you can afford it. If you don’t mind it being super heavy then you’ll love it.

[@Calicultured]

I just picked up one of these for my g85 and the auto focus is horrible! what did you do as a work around for this? touch to focus in manual mode seems to be slow as well...

[@NolanGunn]

So I don't use any autofocus for my videos, everything I do is manual. It's pretty easy to mf on the lens with a little practice!

[@Calicultured]

@@NolanGunn Does the G85 have focus peaking for vids? I'll have to practice!

[@NolanGunn]

@@Calicultured yes it does!

[@bilaf1237]

Vignet?

Photos, yes. Videos, no. 👍

[@DRivers1994]

Anyone try this lens with the commlite speed booster ?

[@NolanGunn]

I havent. I've heard commlite is a bit soft.

[@baqcasanke]

@@NolanGunn commlite sucks. I have the MFT - EF speed booster from commlite. Terrible build quality, infinity focus lost, soft all around, lenses don't attach securely, there is a lot of play and wiggle room which makes the image even softer as big lenses sag a good bit

[@NolanGunn]

@@baqcasanke great to know 👌🏼

can you link your speed booster

You're very welcome!

[@A1Bokeh]

so this is a good alternative to the panasonic 12-35

[@NolanGunn]

Yes! But the 12-35 will be smaller and sharper. Plus you get dual IS.

True!

What are your thoughts on this lens? Would you use it?

[@NeroMC]

i have this lens….but my speedbooster gets some black zone when i move the camera…:/

[@NolanGunn]

What settings are you using? And are you shooting video? I didn't have an issue with my G85. But with photo there is a vignette in 4:3 photo.

[@NeroMC]

@@NolanGunn i ONLY use the metabones for video...i ONLY use this lens for photo on my Nikon...the crop factor is 1.5...i think Canon is 1.6...is your version from Canon?if the câmera is stoped,theres no problem...but if i move it, it appears black spot

[@NolanGunn]

@@NeroMC Ok. Mine was a .71 speedbooster paired with micro four thirds and I didn't have an issue with black spots. Can you show me an example?

@@NolanGunn right now im working.when Im home i Will try to do it...or tomorrow...i would like to show you my gear...we have a lot of gear in common

you still using this lens dude?

No! But i still recommend it.

[@pizzel]

dont you think its helpful to add more photos or videos of sample images especially when you are reviewing a lense

[@NolanGunn]

Probably, yes!

the 18-35 is overrated in my opinion

I think it's accurately rated. It's pretty great!
