I have spent (wasted?) hours going through the various a7(r) threads on this forum and have yet to see any good evidence (ie 50-100% crops) that the a7R produces sharper, crisper, clearer images in the real world than the a7. I also have seen no good evidence as to which copes better with sub 35mm RF lenses. I do wish we could cut to the chase here because it would save so much time. Of course, there may be no practical difference between the two bodies, in which case the choice is easy. Please someone tell me I am wrong here but please back up any assertions with evidence.
The difference in theoretical resolution between the A7 and A7r is 22%. That difference may or may not matter to an individual user but, if the lens is up to it, that difference is visible. Below are 100% crops with the A7r on left and the A7 on right from the Imaging-Resource RAW studio samples. http://www.imaging-resource.com/camera-reviews/sony/a7r/sony-a7rA7.HTM
Same lens used on both. Raw processed through ACR with defaults.
The caveat above though is important because if the lens is not up to it, one will not experience the full benefit of that 22% resolution difference.
My educated speculation is that one will be lucky to see that difference when using adapters or lenses that may not be up to the task. Only with very good native lenses (only the FE 35 and upcoming 55) and probably flawless adapters with exceptional glass will one reap the rewards of the difference IMO.
