I did some whiteboard shots with some of my available wide lenses on the A7R. As expected the 28 biogon did poorly in terms of corner vignetting, smearing, and color shift. I didn't even bother with the 21 biogon which I know is the worst in corner performance. Best 28 was the CV f/1.9 Ultron followed closely by the Contax distagon f/2.8 and Canon FD f/2 (not shown here). The 24mm Canon FD f/2 is also a good performer on the A7R.
All at f/5.6:
21mm f/1.8 Ultron
24mm Canon FD f/2
28mm f/1.9 Ultron
28mm f/2.8 Contax G Biogon
35mm f/2 Contax G Planar
35mm f/2.8 Sony FE Sonnar
40mm f/2 Minolta Rokkor-M
Edit: Just received the Rokinon 14mm (E mount) and added another white card shot and quick test snap. Very little CA, vignetting, and color shift. Distortion for sure, but I need to find the profile I used before for this lens with the D800e.
