Is the A7 better than the A7R at the edges with wides?

Where did you get that from Thorkil?

I think it was from photorumors.com

..and perhaps a FE 85/1.8 together with the 16-35

I have been thinking buying the FE 24-70 for my A7 and have been underwhelmed by the test reports. From a landscape perspective, it doesn't seem to be a good candidate. This picture at Photozone illustrates the point quite well: Sample Image Viewer. 24mm at f11 and the corners are pretty awful.

I then got to thinking about the distinction between the original NEX-5 (14 mp) and the NEX-7 (24 mp). The NEX-7 has brilliant center performance with the kit lens, if I remember correctly, but the corner performance was very weak. The NEX-5 had decent center performance -- about what you would expect with the 14 mp sensor -- but the edge performance was significantly better, despite giving up 10 mp to the NEX-7. See below:

As an initial matter, thank you tashley for coming forward with this information. I'm a little closer to buying the FE 24-70. Nevertheless, does anyone with both cameras and the lens in question have any images that might demonstrate this phenomena that they would be willing to post?

Thanks!
