Canon 5dmk iii to A7s ii

Hey guys,

Looking to get a A7S ii in the coming week.

Currently, I shoot photo and video work, I will be keeping my 5dmkiii for photography and getting rid of my 7D.

I will have the A7S ii for video only and the 5d as a second camera if needed (rarely)

Which Metabones adaptor will I need to use my Canon / Sigma glass on the A7s ii?

What are the pros / cons to using an adaptor, should I just use native glass? (not many options..)

I have some really nice video glass that I'd love to carry over to the A7s ii if there isn't too much compromise.
(eg: slow AF, cropping) When I read about the slow AF, how slow is it actually?

Thanks guys.


Dave Dugdale did a good review of the Metabones and the Commlite Canon EF adapters for Sony cameras...

I use the Commlite adaptor for Canon glass on my a7Rii and haven't had any major issues. Rarely have I had to turn the camera off and on again to fix it and that was never during recording. I would definitely recommend the Commlite adaptor. Sony glass is really expensive and the fly by wire focus is kind of annoying.

Thanks mate, how is the auto focus? How bad is it really, I can't find any examples.

Hard to know with the a7Sii since the AF system is different. On the a7Rii I would say it's quite usable for stills in decent lighting. When the light dims or if you're photographing a surface without much texture it struggles quite a bit. AF for video isn't great and I would never rely on it. But if you're doing a portrait session for photography I would say it's good enough. The focus peaking in the viewfinder is awesome though and you honestly could do a good job manually focusing using the peaking.

I used an a7s and canon's L with a metabones adapter. The AF proved to be slow enough to be unusable. I bought rokinon E mounts and compared them to L glass, and saw no difference. I sold the L glass and the adapter, and kept the rokinons.
