Excellent content, after long time, seen someone doing real time, practical experiment on G9/ GH5 with popular sigma lens. Now I request you, if u can use VILTROX speedbooster with same same combinations and show us results. Rgds
I have the Sigma 18-35mm f1.8 with a Viltrox EF-M2 0.71X speedbooster. I can't get it to autofocus for anything on my G85, but it works MUCH better on my Olympus OM-D E-M1 Mark II because of the phase-detect autofocus of that camera.
Nice comparison! While testing the AF on my GH5s with the latest firmware, I've found that adjusting the custom AF settings does help. I've found a lower sensitivity (-2) and higher speed (+5) seems to work well with native lenses. I'm not sure how that would work with a speedbooster, but I'd be curious to hear your results!
Very good test. I have the GH5 + Viltrox adaptor + Sigma 18-35 & Tamron 70-200mm (G2) and I got a similar test result as you. Auto focus is horrible. Manual focus is the way to go with these combinations.
You are just awesome and yr test helped me a lot. Do me favor, plz tell me, is yr G9 & GH% using latest updated Firmwares or still using old firmwares..?? Tks a lot
Excellent video! I live the Sigma 18-35 but the autofocus is terrible for use on a gimbal. Very unreliable. So I use native panasonics for that work and the Sigma for tripod work. The fact that the Sigma is also not stabilized is also a huge factor. Keep up the great videos, they're excellent!
Hi Mohamed, its not a fair comparisson. Autofocus is affected asweill by the aperture. The Panasonic 2.8 - 4.0 12-60mm not being 1.8F has a total different quality of image result.
I was gonna say the same... No doubt there will be a difference in AF results, i.e. the PL12-60 will be better. But we would have to see the results at F4.0 with the Sigma to really compare it (since the PL doesn't have F1.2 and you shot that lens at F4.0 and not even F2.8)...
I recently started testing my sigma 18-35mm on my panasonic g9 with viltrox adapter. I'm trying to use it with my stabilizer for some nice shallow depth of field shots while walking. Surprisingly enough, AF does well enough to get a few zoomed in stabilizer shots.
I have had similar experiences. Sometimes it autofocuses rather nicely, but it's just inconsistent enough for me to not rely on it. Some of our shoots are so hectic, that repeating a shot because I was relying on autofocus is not worth it.
@@FabledFew I used it yesterday with my gimbal and did a few zoomed in shallow depth of field shots with my stabilizer. It worked good. You're right though, af with that lens can't be trusted enough to use for long.
Thank you! With GH5, it'd be around 2.2KG, and with G9 it'd be 2KG. It's not suitable for handheld work, especially long weddings. But put it on a tripod, and you get beautiful results. Check out my review for the 50-100mm.
@@professionalpotato4764 Yes, of course ... but somehow it is comparing the F4 shots with the F1.2 shots for AF performance. I feel that the result will be still much worse with the Sigma, but it is a bit of an unfair comparison in general? Or at least get a native F1.2 lens to compare and not the F4 lens, where by default more is in focus...
Nice video.. i have one problem facing since long maybe you have some idea. Actually when I record on my lumix g9 with any 25mn 1.7 or kit (12 to 60)and in post the video gets shaky. Actually I.record 60fps and slow down to 24fps and my all footage gets shaky/distort especially when I reverse the clip. I don't know its camera setting fault or stabilization setting issue .(I turn on I.S lock with handheld) or premier pro fault. But its too irritated..can you help me out..already subscribe:-) plzzz
You shouldn't turn on IS Lock if you're moving the camera. IS Lock is for fixed, non-moving shots where it gives you that tripod stable look. If you're moving the camera with IS Lock it causes heavy distortion and warps.
The Sigmas are EF lenses, being adapted to MFT using the Metabones Speedbooster Ultra EF to MFT adaptor. The lenses were designed for DSLRs, and hence do not work well with the contrast-based autofocus system of the Panasonic cameras.
So, the native 12-60mm f/2.8-4.0 lens + speedbooster is the best combo? Or what I'm saying doesn't make any sense and the footage we have seen on this video with that lens was without the speedbooster? Sorry for the noob questions, just looking to get my first hybrid camera and make the best choice for the lenses!
Native lenses don't mount on speedboosters, since speedboosters are lens adaptors inherently. For the fastest focus acquision, I would suggest native lenses. :)
What should be the sense of this ? - We all know, that the autofocus system on Panasonic is not far away from being total crap - no matter, what lense you are using. True, the Sigmas are even worse compared to native mft lenses, but this is the result from many points coming together...

Its exactly the same results. I have both the viltrox and metabones speedboosters. They perform exactly the same in my experience.
I have the Sigma 18-35mm f1.8 with a Viltrox EF-M2 0.71X speedbooster. I can't get it to autofocus for anything on my G85, but it works MUCH better on my Olympus OM-D E-M1 Mark II because of the phase-detect autofocus of that camera.
czcams.com/video/iGMY4YRTk0E/video.html&ab_channel=YodaYeo Found the solution I hope you are still using that camera.

This is EXACTLY what I was looking for.
You should redo this with the new update

Thanks for sharing! How is the build quality of the Viltrox adaptor? How does it hold up when paired with the heavy Tamron 70-200?
You are just awesome and yr test helped me a lot. Do me favor, plz tell me, is yr G9 & GH% using latest updated Firmwares or still using old firmwares..??

thank you so muchhhhhhhhhh thanks a lot.....this content is very help full i was going to buy this combination for g9
Glad it was useful to you! Thanks for watching.
Great job on this video and so many of your others. New sub, keep it up.
Thank you for subscribing!

your viltrox adaprer is speedbooster right?
Hello friend, thanks for the video, are there differences in quality between Nikon or Canon Mount for 18-35? Or is it the Same thing?
Good job! What is the wieght of this sigma 50-100 and the camera? Is this set up good for wedding video maybe handheld or tripod?
Thank you! With GH5, it'd be around 2.2KG, and with G9 it'd be 2KG. It's not suitable for handheld work, especially long weddings. But put it on a tripod, and you get beautiful results. Check out my review for the 50-100mm.
@@FabledFew sure thanks
I think we must compare those lenses on canon R7 which is much popular for its autofocus speed
Great Video, very informative!
Is the AF performance improved with latest firmware on the G9?
Not with adapted lenses, unfortunately.
I wonder how an Olympus OMD EM1 III would fare, my OMD EM5 lll has better auto focus than my G9.
I'd say it'd fare better, since it has phase detection autofocus.
Quality content. Keep it up!
Thanks for watching!
what about no speedbooster just a normal adapter to sigma apsc lens . will the AF improve?
The limiting factor is the camera here, so I don’t think the adaptor will make a difference.
great work!
thanks for sharing， that is the exactly video I need.
so when I am going to shoot video on G9+sigma I have to get use to manual focusing😂
It's pretty easy once you get a feel for it! Plus the Sigma lenses have mechanical, linear manual focus with a buttery smooth focus ring.
@@FabledFewThanks，this video shows the G9+sigma has very good video quality on daytime
Also helps if you film in F4.0 like the PL12-60 instead of F1.2 :P
@@funtomias But that would give it f/8 DoF, no more bokeh. Everything would be in focus.

@@FabledFew thanks for your reply .I follow your instruction ...regards
So I'm new to this. Is it thr speed booster or the sigma lens that is messing with the auto focus?
The Sigmas are EF lenses, being adapted to MFT using the Metabones Speedbooster Ultra EF to MFT adaptor. The lenses were designed for DSLRs, and hence do not work well with the contrast-based autofocus system of the Panasonic cameras.
@@FabledFew oh are there any sigma lens for the four thirds g9?
Yes, there are three. 16mm f/1.4 - 30mm f/1.4 - 56mm f/1.4. All are super sharp.
is the G9 on the latest firmware?
Yes, it is.
So, the native 12-60mm f/2.8-4.0 lens + speedbooster is the best combo?
Or what I'm saying doesn't make any sense and the footage we have seen on this video with that lens was without the speedbooster? Sorry for the noob questions, just looking to get my first hybrid camera and make the best choice for the lenses!
Native lenses don't mount on speedboosters, since speedboosters are lens adaptors inherently. For the fastest focus acquision, I would suggest native lenses. :)
@@FabledFew oh okay, thanks for clarifying!
I think this is intentional that not native lens works so bad on the Panasonic body - people will be forced to buy native lenses. Simply.
It would be great if you you do same test for eos r and eos rp
I do not yet own any of the R cameras, but if I do come into possession of one, I will!
I already knew the results. I just came to see the shit show. 🤣🤣 I have the 18-35 and the GH5s and G9.
Ahh, a fellow sufferer 😂
What should be the sense of this ? - We all know, that the autofocus system on Panasonic is not far away from being total crap - no matter, what lense you are using. True, the Sigmas are even worse compared to native mft lenses, but this is the result from many points coming together...
well done!
has anyone tried this on a em1 mkii? is it any better?
Can do with g85 ?
It's a bit slower with G85, and of course face detection isn't as good as the G9.
Speedboster is good for video but probably not for photo. I's wrongh?
Yeah, it's much better for video use.
Nice
great, thanx
Thanks for watching!
Use a proper camera.
