DPReview Test Video:
A7RII支持所有对焦模式: eye AF, lock-on AF. 视频里的PDAF等等...
能用Eye AF和视频对焦太好了，如果转接Canon的镜头也有同样效果,那就太叼了。

35f2那个是装在metabones上测试的好伐，别弄混了。

What does it do if you use the MC-11 between an A7Rm2 and a Canon made EF
lens like a 35 f1.4?

We're not quite sure yet - we haven't been able to test with all sorts of
Canon lenses. With a Canon 35mm F2, though, while all functionality was
maintained (Eye AF, Lock-on AF, etc.), the camera tended to resort to CDAF (
hunting) as opposed to PDAF. We're not sure why, but it may have something
to do with that 'internal database' - we're not sure Sigma maintains it for
non-Sigma lenses. This is just a guess though.
