Having used this combination with a GH5 for more than a month, other notes I'd like to share is that at widest focal length, there will be some weird softening and distortion to the edges of the frame. And the Sigma 18-35mm also has quite a hefty weight, so if you're always shooting things hand held, or need to travel around carrying this camera, you will get tired quickly carrying this thing and your hand might shake while shooting because of it. So I'd opt for native lenses when going on shoots where I need to walk around a lot. Another is, unlike Leica or Olympus lenses, the lens flare can be quite pronounced if you're shooting into the sun or strong sunlight, with green streaks running across your frame. Can be great if you like the stylized flare look, but otherwise, be careful. The aperture can't also be closed more than f/11 so be ready to use ND filters or bumping your shutter speed up if you're shooting under the sun. Otherwise, the lens is quite sharp compared to lots of native m4/3 lenses, and quite versatile for what it offers (zoom range with really low aperture). These are from my experience from my short time using it, so probably need to use it more to know what it is actually capable of.

This was literally the video I was looking for. Excellent video!

I’ve been using mine for a couple weeks now on the G9. For stills it’s pretty decent, for video not so much. A few things I’ve noticed: 1. The 24-105 L works in good light. In low light it will focus but the camera won’t take a picture. You can hear the shutter go off but it doesn’t record to memory card. 2. The 35mm 1.4 L II shot wide open at f1 is very soft and hazy. Doesn’t seem to reach critical focus under any light. 3. The 40mm pancake, the 135 L and the 70-200 L II all work great at any Aperture and any light.

The exact thing I searched for after the Lumix G9 information brought me right back to your channel. Subscribed!

Thanks for the video! I've used the Metabones Speed Booster 0.64 XL with Sigma 18-35 on Panasonic G7 for a year. I have just bought the 0.71x Metabones Ultra for the GH5s. Speed Booster + Sigma 18-35 is a killer combo even on cheap cameras like the G7 (that I have retired a few months ago). I didn't try the Viltrox but I would rather pay more to have an excellent all-around performance from Metabones speed booster even though it is ridiculously expensive.

I've got the G9 and the Viltrox EF-M2. I find the looseness (play) of both mounts to be a real turn-off. I put it down to the fact that the unit is so cheap. There's sloppy movement between it and the lens as well as it and the body. So this adds up to not such a great experience when focusing manually. The autofocus in two of my canon lenses is no where near as good as you had with the sigma. I have more lenses to test with and I will upgrade the firmware before commenting further about that. Overall it was the adaptor I could afford. The I'm not going to pay US$700 for a lens adaptor. I am also impressed that Viltrox has a nice piece of glass in there that maintains clarity. My Canon EF 135 f/2 les is a good test for that. The G9 is amazing, as usual. I love using it. The Viltrox allows me to use my beloved Canon glass, so it makes me happy. I hope that Viltrox will tighten up it's tolerances with a new release. I would buy it if they did.

After watching several videos on the improved AF in the G9, I ordered one that will arrive on Friday. It seems to have better autofocus than the GH5 from the 2.0 firmware. So, I'm looking forward to shooting with it. I also own the ZCam E2C, the BMPCC4K, the Metabones x.71 speedbooster, as well as the Sigma 18-35. Along with Canon glass and more native MFT lenses. But, with G9's AF and stabilization, I'm looking forward to using it as a run and gun camera.

If you want to use vintage lenses tape the ef-m2 to body connectors. This is fantastic tool with Carl Zeiss Jena Flektogon, Tessar etc. When you add the GH5 IBIS those old lenses becomes a treasures.

A very good review. I find the combination of the Viltrox and a 50mm f1.8 Canon STM lens, as show briefly in your video, to be a very good portrait lens, making a 71mm f1.3 equivalent for the bokeh look, at much less than an f1.2 Nocticron! The Canon 70-210mm f2.8 becomes approximately a 50-180mm f2 lens too. A very useful accessory.

I own the g9 and use it with my gimbal. G9 with the Viltrox and tokina 11-16mm looks amazing!

as someone who still manages to get great images with my g7, i look forward to adapting my full frame canon glass. thank you for the effort and the sharing. i am a very appreciative subscriber. thumbs up.

uses exact same thing but the hunting of the lens making too much noises and never ending have the motor sound, is that normal?

I too have recently bought the Viltrox but have only tried it with my Canon L lenses (I still have my 5Dii, but don't use it all that much any more). I have to say I've been very pleasantly surprised by the performance - it doesn't appear to impair sharpness to any appreciable degree. I wasn't expecting much from AF performance, so the fact it works at all, albeitly slowly - is a bit of a bonus. I can't for the life in me imagine what would make the Metabones alternative worth around five times the cost of the Viltrox, but I haven't been able to make a comparison. I was considering whether or not to jump the MfT ship due to the increasing costs of some very ordinary lenses [or very costly ones] from the OEMs. I mean what the hell is the point of a constant f4 zoom [especially when it's hugely expensive] on an MfT body? The idea of an 18-35 f1.8 x 2 x 0.71 is appealing however, in spite of the weight - considering the price. That works out roughly in equivalence terms to 25.5-50mm and f2.4 - still a very useful optic to have especially if you like to isolate portraits/groups [and I do]. I'm now seriously considering buying a G9 or an EM1 mkii I find it quite refreshing you don't fall into the bullshit territory of many MfT shooters who are more than happy to accept equivalence in focal length, but insist it doesn't apply to the effect of equivalence on aperture either in DoF, or overall light gathering [and therefore noise]. Nice also to see Prague and Bratislava prominently featured in your videos - two of my favourite cities to visit. This is only the second of your videos I've seen, but I'm going to go ahead and subscribe. Thanks.

Well documented review. As always!

Thanks for the review. I recognise the beautiful Bratislava.

Kinda changes, thats the kind of explanation that clarifies everything for me. The Day I buy a Viltrox product is the day I chuck my GH5 in the pool.

I'm using the g7 with EF-m2/sigma 17-50mm f2.8 (adapter makes it 24-70mm f2.0) Excellent combo! Also soon will be using another ef-m2 with tokina 11-16 f2.8. Using these for video only in my wedding gigs. I paid less than $135 each for both adapters on ebay through different sellers.

I think one of the reasons I like speedboosters the most is because I don't need to worry about exposing the sensor when switching lenses. :)

Does the viltrox ef-M2II work with the sigma Canon 18-35 EF-S Mount or just with the EF mount?

How do you know if you need to re-adjust the Viltrox

Great Review again man! I love your videos, really enjoy it everytime. Very practical tips and helpful information. I use a similar combination: Lumix G81/85 + Viltrox EF-M2 + Sigma 18-35mm F1.8 and I am very happy with it. BTW thanks for tip for removing the vignetting at wide angle!!! Keep going

My viltrox is too soft when wide opened. I have to stop down at least one stop to make it usuable. Adapter is adjusted for focusing to infinity. Metabones is sharp even at f1.2.

What’s the best settings with this combo for photography

Does the July 12th 2024 firmware update work on the G9ii?

Love your videos. But was wondering if you still have the Panasonic GH5 and does the Vitrox work ok with it. And can the Canon 15-85 lens work with it.

I have purposely bought a new canon mount sigma 18-35 f1.8 for my G7, along with a Viltrox EF-M2 adapter. This is the best and affordable setup for me at the moment. I didn't buy any of the prime lenses of MFT because at 1.8 they are not letting enough light into the sensor in dim environment. However there are 2 cons of this setup: 1st is the weight of the lens + my Ronin-m is killing my arms 2nd is the mount of G7 is too soft to handle the weight of the sigma thus my G7 lens mount is kind of loosen up. Although this hasn't affected the quality of the video but i doubt that my G7 will last long if I continue to use it for another 6 months. Otherwise, the performance of this combo is excellent!

im thinking on getting the G9 because overall it is a complete package in terms of photography features and video features and quality, my only downside is the size of the sensor in terms of low light performance and such, does this improve the G9 ? i was looking at canon cameras but none of them have the same features of the G9, so right now the G9 is top 1 option for me.

I have an olympus 14-42 mm f3.5-5.6 will the adapter make my lens faster? Or it only works with canon

hey i have a question, when you mount the lens on the adapter does it do the click sound? i bought my speedboster and received today, but whent i tried to mount my 18-35 it does not lock completly, doensn't do the click like my other spedbooster fo M mounts. i have the same adapter and lens you have.

I recognise Bratislava! I was there a year ago or so. Lovely city.

Does the sigma 18-200 dc os hsm compatible with viltrox ef-m2?

Great video for those looking for more versatility 💯👍

Excellent information about the Viltrox.

Mine doesn’t fit the lens for some reason

Great video - thanks a lot !!

I purchased the Viltrox EF-M2 Speedbooster and returned it few days later because it was a disaster. It had back-focus issues with all lenses I tried... when the camera (GH5 & GX9) got a focus. Unfortunately, it is not easy to focus correctly with Viltrox. When focusing on the same subjects it may get a focus or may not, so you have to press the shutter or AF bottom several times. My copy didn't work with Canon EF 100mm f/2.8 Macro and had some issues with EF 50mm f/1.4. It worked with EF 35mm f/1.4 L and EF 17-40 F/4 L (but still with back-focus effect). I updated the unit with the latest software, but it didn't help. It seems that it's possible to correct the back-focus issues by adjusting the position of the optical element, but to my opinion it should be done by the manufacture and not by the user. I contacted Viltrox support in order to find a solution to the problem, but got an answer " ...We understand you want to solve this problem as soon as possible. But we have so many compatible problem of many new lenses need to be solved one by one. It will take a much longer time. We also hope we can solve your problem soon. But it is really hard to solve these problems, our engineer need to test and change the program..." All the lenses I used are listed as compatible on Viltrox website. It was enough to return the unit and not longer look at this company. As for video use - just forget it. It's not possible to use the camera in autofocus mode, because the lens is constantly hunting. One more thing. I found GH5 + Viltrox + Canon EF lenses such as 24-70 f/2.8 or 70-200 f/2.8 combo is ridiculously heavy and uncomfortable with small MFT body. I was afraid that the weight of the lens could deform the bayonet of the GH5. Finally I decided to stay with MFT lenses. May be In the future I'll try Metabones to adapt Canon's TS lenses to Pana camera's. But is so expensive for such a limited use...

Which do you recommend more for a first lens, the Leica 12-60 f2.8-4.0 or this combo?

I literally bought a gh5 with my 18-35 sig but my lens not fitting.... it feels loose

Thanks for doing this review. I always trust your videos. I am waiting for the 10-25mm Panasonic lens but now thinking the Signa 18-25 with Speedbooster could be a better, more versatile, choice? Do you think this combination would be good as a travel lens? My thinking is to use this combination as a daily lens that I would leave on the camera and will also work in low light. I would never use it for vlogging type video but do want to use this for travel photos and video with a G95. My only other lens is a 50-200mm. This combination is heavier than the Panasonic. Do you think it is too heavy for travel? I appreciate your thoughts!! Thanks again!

0:50 *It turns the 50mm to about 70mm instead of 100mm w/o the booster.

This is my setup. Great video.

Hey Hybrid Shooter, I have the A7iii and a GH5, and so I’m thinking of getting the Sigma 18-35 for the Sony, and then an adapter to use the Sigma on the GH5. Do you see any problems with that? What adapter might you recommend for this case? Thank you!

Please tell me, is there such an adapter on Sigma with Nikon mount?

Thank you!

I am not sure but I do believe that the gain in aperture you get from a speedbooster does not give you any extra dof. You will get more light, but its not like an actually extra stop. I could be mistaken though. Does anybody know for sure?

Appreciate you can share some raw file of the picture ?

At 2:43 it affects me only when i use Sigma 50-100 f/1.8 with tripod plate on the Lens...many times i lost the horizon and i fix it in post..For studio photography its a little bad but i deal with it

Hi i bought this adapter too, but recognized, that every lens, longer than 25mm can not focus to infinity on my BMPCC. I tried all these lenses (highspeed primes from Zeiss, Leica, Nikon with adapters to Canon EF) with a plain adapter (without optical elements) everything is fine. I doublechecked with two different Canon DSLRs, focus to infinity is no problem. Only with this adapter, it’s not possible. Do you know, if there is there a way to adjust the adapter for this reason? I know that metabones speedbooster can be adjusted.

Any problems with it making your camera freeze? I was happy with this speed booster until it kept making my camera freeze and I'd have to take out the battery to even turn it off. Tried updating firmware and nothing changed.

Hi! I know this is an old video from you, but I want to know what is your advice about Sigma 18-35 f1.8 and Olympus 12-40 mm f2.8 pro? I want to buy one considering as the Panasonic kit lens 12-60mm f3.5 is limited capabilities.

Can you do a video on Lumix G80 please on using the adepter

I was looking for a video on the viltrox/sigma combination and you had exactly what I'm looking for. I think it's odd that this type of thing happens quite a bit with your channel. Also very informative! Is it possible that a longer lens would auto-focus better than this Sigma? It would seem that the hunting would be less noticeable because there would be a larger margin for error.

After using Viltrox NF-m43x with my old tamron 17-50/2.8, I see no reason buying Metabones Speed Booster for 8x times higher price. Images are very sharp with a good contrast.

nice! however from reviews and forums I came to know that the Metabones is much higher quality than its rivals. a bit expensive though.

Hello, Great review. I have this combo but with G7, however there is a lot of focus hunting w/ the sigma18-35mm. Any recommendations? please?

I have searched this video... need some advise. I have this exact speedbooster and sigma combo on gh5 with the latest firmwares but I can not change aputure in camera or on Speedbooster manualy. Any help?

There is new viltrox m2 for canon m serier efm soeedbooster adapter Can you do a video of canon m50 with viltrox efm m2 with canon lens and compare autofocus,low light,4k ,built quality

Great video. Please!!!, review of viltrox speedboster adapter for sony 6500.

Thank you for this info, very helpful. For my G85, I'm trying to decide between the Metabones Ultra and other boosters. Any advice would be much appreciated!

Ahoj ! Poprosim o radu ak budes vediet pomoct. Mam lumix g9 a mam problem ze po istej dobe sa mi samo odseba prepne automaticky hladačik s prepinanim na displej. Prepne na displej. Znova ho nastavim na prepinanie hladacik,displej a po nejakej dobe cca 200 zaberov sa znova prepne na displej. Nevies v com je chyba? Dakujem !😊

I want to tey this too with my EM 10iii and G7. Hope for the best.

So does the adapter effectively make this about a 16-30mm (32-60 equivalent) lens?

Great video. Can you do Viltrox Speedbooster on Canon m50 with sigma 18-35 test???

How is it a 1.42 crop factor?

You sound like a bond villian 😅 but you are to the point and give awesome details.

Hey! Big fan of your reviews, but does the Sigma lens work with Image App?

Thank you. 2 questions. It seems it does the same job so why oh why is the Meta Bones so incredible expensive in comparison. ALSO. What video do you have the explains the best way to use the auto focus. I have GH5 and GH6. I would really like to see it. Is there any chance you'll do one for the GH6. I'd pay for that video. I would. Thank again.

I have a Panasonic G80 ?, Sigma 18-35mm F1.8 DC Art lens with Nikon mount.

Does Viltrox make the .64 speed booster?

Pekny pohlad na Hrad a Most SNP..😎👍

Hello, I just bought the lens and the viltrox, is it normal to hear it inside the lens when the aperture changes?

Does the Viltrox ship with a cable for updating firmware? If not, what cable do I need to purchase? Thanks

Hey man thanks for this video! I was wondering how this setup works with the prefocus feature when in manual mode? Does it still work?

I am about to try out an old Pentax 18-35mm with an adaptor on my Lumix G9. I am starting with a very basic adaptor, just to see how I like the idea. When you turn the camera on, it asks what focal length...but with a zoom what number do you put into the G9? The longest focal length, the shortest, in the middle, or something else? I am curious if anyone knows the answer?

Ahoj díky za tvé ve videa, hlavně o fotoaparátech Panasonic. Mám na tebe dotaz. Zakoupil jsem si teď na natáčení Lumix GX80 spolu s objektivem Leica 12-60 2.8-4.0. Jsem moc spokojený, k tomu jsem koupil ještě gimbal Moza Aircross 2. Trochu si prohrávám s myšlenkou objektiv prodat a koupit Viltrox Speedbooster a Sigmu 18-35 1.8. Natáčím občas i v horších světelných podmínkách, tak clona 1.2 by se hodila. Nadruhou stranu Leica je lehčí a bude mít lepší autofocus. Co by jsi mi doporučil ty? Tu Sigmu se speedboosterem nebo si ponechat by Leicu. Díky moc.

What do you think is the best quality lens option for GH5 for commercial work. Speedbooster+Sigma and other / Olympus Pro Series f1.2 mft or maybe voightlander ? Ps. Yours review are always good ;)

I"m wondering how it compares to the zhongyi turbo lens II?

so if i would take a full frame f1.2 prime it would be an f 0.6 lens?

What do you think about using this combo on Panasonic G80? I was considering buying Sigma 16 mm 1,4 but it is not wide enough for micro 4/3.

hello, i would like to know if you recommend this setup for portraits photography with two adapter the viltrox and a normal for the 70mm

So instead of buying panasonic 12-35 mm f/2,8 I can buy this combination and I will get even better results because of speed booster. If I'm correct.

Have you proven a EF-S Lens with the Viltrox Speedbooster? Chiers! Good Video!

So, does this speedbooster fit the E-M1 II and/or the G85? I know there have been some compatibility issues with the Metabones speedbooster.

Thanks, didn’t know this was “a thing”. Too bad I sold off all my Canon L gear, I could use them with the G9 I haven’t purchased yet. I can say your channel is making it harder for me to resist getting a G9.

What would be the best lens/speed booster for astrophotographers?

Is the sigma a focus by wire lens yea? How is the easiest way to tell if a lens is full manual or focus by wire. There's no clear information of this online

Would LOVE to see these results with the new g9 mark 2!

The AF just works with the Canon version, not with Nikon lenses!

Hello. You are using a Panasonic Lumix GH camera and a Sigma AF 18-35mm lens with a Viltrox EF-M1 adapter. If you focus on the subject, and change the focal length of the lens (18 - 35 or 35 - 18). Does the subject remain sharp? The sharpness disappears on my camera, and I need to focus a second time. When using a Panasonic 12 -38, 2.8 lens, there is no such effect. I change the focal length and the subject is constantly in focus. What do you think is the cause of the effect with Sigma AF 18-35mm.

have you used this + the sigma lens on the g80 does it fit and whats it like?

Hello, first, it's a nice review ! Now my question, for stills, what is the best pick, the Oly 40-150mm f2.8 (1200€) or the Viltrox EF-M2 with Canon 70-200mm F4.0 (for 750€), this should be something like 100-280mm f2.8 on my Panasonic G85. Size and weight is not a problem, i want to shoot some rugby, mainly by daylight.

This adapter does not fit my sigma 18-35mm lens

Hi! How would you compare image quality of this combination vs. Leica 10-25. I saw a comparison recently where there was much more softness on the edges of the image with Sigma on Viltrox. And tonnes of chromatic aberration. Could it be caused by faulty speedbooster? Did you regulate your speedbooster somehow before use?

hey, would you expect similar autofocus performance on a G80 for shooting stills? the speed that you've shown in the video is completely fine for my needs, but I'm worried if my G80 would perform worse.

my viltrox ef m2 II is crashing my G9. any suggestions regarding that? it works well with my old GX1. but it makes the g9 crazy

That's why phase detect AF is important, especially when you adapt DSLR lenses.

Are you having any issues with vignetting? I have the viltrox ef-m2ii with sigma 17-50 f2.8 on my g85 and getting heavy vignetting in 1080, more when the camera moves. Have you seen this?

If I use my Canon 16-35 2.8 on this with a G9 would it work?

No ano ale ako je na tom Viltrox v protisvetle? To nikde nieje poriadne vidiet.... Ake mas ty s nim skusenosti?
