Introduction

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.

Whoa! The Sony is horribly soft on the sides with this lens.

 

Analysis

I didn't show the center crops, which are about the same as each other. Neither camera is much sharper than the other in the center.

Where the Sony falls apart is at the sides with wide lenses. I showed this at Sony A7R II & LEICA 21mm f/3.4 ASPH versus Canon 5DSR & 20mm f/2.8 USM, and the Canon was much better — even with a much crummier lens.

Wanting to compare the same lens on the two different cameras, I ran this test again, and the Sony looks downright broken at the sides. I expected better, since I was using an SLR lens to make it easier for the Sony to perform in the corners, but again the Sony looks horrible.

I also compared with the Canon 50mm f/1.8 STM, and they looked pretty much the same.

The problem is that the Sony is horrible with wide lenses.

Adapters make the Sony fun for hobbyists, but if you need the best images, it's always better to shoot lenses on the cameras for which they were designed.

Normal and tele lenses should work well, but sadly wide lenses uniformly have looked horrible on all Sony mirrorless cameras on which I've tried them. I also showed this years ago at Sony A7 versus LEICA M240 vs. Canon 5D Mk III w/LEICA 21mm f/3.4 ASPH& 20mm f/2.8 USM.

If your work doesn't involve wide lenses, then have at it, but forget it if it does.

Of course I prefer the speed and ergonomics of the Canon lenses as shot on Canon cameras, but in this case the pictures are so bad on the Sony that this shouldn't even be an issue.
