Ken Rockwell is a unique voice in the blogosphere and I like his stuff very much, even when I don’t agree with him. But it’s hard to argue with his latest analysis. He offers yet another proof point that the Sony a7r II [B&H|Amazon] now focuses Canon glass [B&H|Amazon] as quickly as – maybe more quickly than – native Canon bodies, yet offers the startling conclusion that the resulting image in the corners with wide angle lenses is… terrible.
Take a look for yourself, and tell us what you think in the comments below. Valid? Have you experienced similar results (he says this is only a problem with wide angle lenses)? Different? I wonder how this might figure into the Sony E-mount glass coming from Voigtländer and Schneider Kreuznach in 2016.

How well do Canon lenses work on the Sony A7R II with an adapter?
Let's see how well the same Canon lens performs as shot on a Sony A7R II with a Fotodiox adapter as compared with being shot on a native Canon 5DSR.
The good news is that the EOS lenses handle great with the Fotodiox adapter: autofocus and VR all work as well as on the native Canon cameras. Of course the ergonomics and color rendition peculiar to each camera remains the same.
These are shot with the same Canon 16-35mm f/4 L IS at f/4 at ISO 100 on each camera.
