I have been watching the a7 and a7r threads. I would like to use my existing canon lenses, could any of you that has a A7 and a canon 70-200 f4 IS, does it auto focus using the metabones iii over the full range ? And if Yes, what is the auto focus like ? Many thanks in advance.
Also 17-40 f4, will it auto focus ok
I am using the Sony A7R with the lenses you mentioned above and with Metabones III adapter. In both cases the AF works fine, just a bit slower compared to the lenses each mounted on a Canon camera FF body. AF works on the full range of the 70-200 lens. The IS of the 70-200/4 IS lens works exactly the same as on my Canon 5D MkII body, I didn't observe any difference.
