Stab Posted September 18, 2018 Share Posted September 18, 2018 Is there anyone here with the GH5 / GH4 that shoots with the Sigma 18-35 on a (Canon) Speedbooster and can tell me something about the autofocus when taking stills? Is it accurate? And is which mode is it working the best? Would I be able to trust it for shooting stills? I shoot with the Nikon version of this setup now, thinking I would never need to shoot stills, but since recently I get asked a lot to shoot stills. And I love this lens / combo. Anyone who has tested it or could test it for me? Thanks! Thpriest 1 Quote Link to comment Share on other sites More sharing options...
Anaconda_ Posted September 18, 2018 Share Posted September 18, 2018 If you already shoot with that setup, why not do your own tests? Quote Link to comment Share on other sites More sharing options...

Because I have the Nikon version of the Speed Booster which doesn't have any electronic connection to the camera. Therefore I cannot use autofocus heart0less and Anaconda_ 2 Quote Link to comment Share on other sites More sharing options...

Sports have entirely different requirements to portraits or travel photography. I use the Viltrox+Sigma (EOS mount) setup. First time I tried it for stills, it reminded me of the time I was using the EM1mk1 with the Viltrox FT to m43 adapter and Olympus 14-54mm f2.8-3.5 mk2. Quite snappy but not spectacularly fast. I'd say at the same level as some older native m43 lenses. If I use the setup for stills it will be for static subjects, so, again, depends on your application.

buggz Posted September 19, 2018 Share Posted September 19, 2018 I can't remember as it's been a while, but I remember it worked okay for portraits, traveling, etc. GH5, 0.67XL Metabones Speedbooster, Sigma Art 18-35/1.8 I use this combo all the time for video, high school football half time shows.

Thpriest Posted September 20, 2018 Share Posted September 20, 2018 I have tried it a couple of times and it seemed reasonably accurate but not very fast. Stab 1 Quote Link to comment Share on other sites More sharing options...
