Testing Sigma 18-35mm on GH7: Autofocus Disaster?

Metabones just put out a firmware update and I really want the autofocus to work with the Sigma 18-35mm f1.8, the ULTRA 0.71x Metabones Speedbooster and the Panasonic GH7. The GH7 features the new LUMIX hybrid phase detect autofocus that works great with native MFT mount lenses like the Leica 10-25mm and 25-50mm f1.7 but how does it perform with the GOAT GH5 lens, the Sigma 18-35mm with the Metabones Speedbooster.

Dude I'm pretty sure you overlooked this sentence in the firmware update guide: "Please ensure the checkbox "Combine OIS and ES for Panasonic" is unchecked". I've tested my GH7 with all metabones adapters (0.71, 0.64, smart adapter) at the newest firmware with lenses sigma 18-35, sigma 40art, canon ef 24-105, the autofocus all works flawlessly.

This video misleads lots of potential users because of the mistakes on updating the Metabones adapter, the user error is hard on this one, my advice is to put it down, this just keeps the bad reputation about the autofocus for lumix cameras.

DUDE !!! your GH7 is in AFS (single auto focus)! change to AFC (continous autofocus) the problem is in your camera settings

[bezolio_bee]

Maybe you missed a step updating the firmware - try this? " •Make sure that the ”Combine OIS and ES for Panasonic; legacy AF for Olympus; disable AF for Blackmagic" is turned ’OFF’ in the software menu when you have the speedbooster connected to the computer. Otherwise the PDAF will not function."

Having seen this combo actually work in person, and pretty damn well at that, I look forward to the follow-up video after you check the correct box before upgrading. Hopefully, you'll do it soon, as this video is high in the search and is creating the wrong impression. Regards.

Unsubscribed. You had half a year to admit your user error. Probably leaving this video up for cheap engagement. People like you are the reason people hate influencers.

Clearly he didn't do the update properly or there is some issue with his particular lens. Make sure the right boxes are checked as per the instructions given on the updates. The AF isn't perfect but it at least focuses unlike what's shown in this video

Hi Caleb
Use the 18-35 with S5iiX and Sigma Adapter it is working great there...

[TheFlyFishingFilmmaker]

Interesting though I've watched other videos where it worked fine ...

[FluidSurfing]

4'45 so dramatic and cinematic sequence 🔥

Thanks metabones that they did the update to solve this.

Great video

[Khuongreview]

I hope this get a fix soon for GH7, love mine on ZV-E1 with MC-11. Work like a charm.

[Svenfrederikson]

I uncheck all of the options in the checkbox on my Speedbooster Ultra, and the focus works pretty good with the Sigma and the GH7. If you check all options it will not work for some reason.

Did you know there’s a new Viltrox speed booster that dropped like 3 days ago for MFT.

Apparently brand new AF and it works better.

[JericGambon]

Apparently there's a certain setting combination in order to make CAF work. I've seen two videos where the AF works perfect with the metabones update

[alejandrocastillo]

The gh7 was clearly shy for it's first few auto-focus moments. It'll get there ;)

[thedondeluxe]

This lens focuses like a frickin' dream on my Canon R7 with the EF-RF adapter. It performs better than ever! Not sure what's going on here, but I would assume it's the speed booster?

[universalhealingspace]

you might have to adjust the glass on the speed booster

[NeilD]

To be fair, I had this same issue after installing the Metabones firmware, that software package is absolute dog sh*t, the check 'boxes' are not boxes and there's no visual prompt in there to suggest any of the options are able to be toggled. I'm 99% sure that OIS setting was unticked anyway when I upgraded, but mine didn't work. I had to downgrade to 4.10 then upgrade again to 4.20 where the setting was off by default and now it works.

[uliyanoff_films]

I use the same lens and speedbooster with my GH7. Autofocus works wery well with AFC mode (not AFS).

The continuous autofocus for video of Sigma 18-35mm f1.8 works fine on my S5IIX using Sigma MC21 and Viltrox EF-L Pro Adapter
