Personally, if you are going to mod your A7R, why bother with the Ultron if you\'re after sharpness? WO, it\'s so personal that it\'s hard to say which is better. Heck, if anything, the CV 35/1.2 would be among the top as well.
I\'m not sure I follow. The Ultron is a very good lens and stopped down just a bit is IMO impressive across the frame (on Leica M). I haven\'t compared it directly against the ZM 35/1.4 but would be surprised if there is much sharpness difference.
I think rendering character would be the bigger differentiator.
As for the 35/1.2... I don\'t believe it\'s as good as either. It suffers from greater field curvature than either the Distagon or Ultron. Perhaps by happenstance, that field curvature is counteracted on unmodded Sonys by the thick cover glass, making it one of the better performing RF 35s. Mod the camera and it will be a worse performer. If I recall my tests of it on the M9/M240, it needed to be stopped down a bit (~f/5.6) to bring up the edges and corners and never really had the bite one would expect of of a ZM lens. IMO, the Ultron has better bite than the 1.2.
Yeah, it\'s going to come down to personal preferences.
Bottom line for me is I\'m happy with the Ultron as an all purpose lens for ~$650 US imported. The ZM is possibly nicer in respect to some Zeissy rendering characteristics, but for me, not worth spending nearly 3x more.
