Chuck, I have thought of that. I've read varying accounts about the compatibility of 35 crons both pre-ASPH and ASPH and whether they really work well on the At/r. If I was sure a pre-ASPH cron would work really well that would be my lens of choice.
I have a C-Summicron 40/2 which is very good on both the A7 and A7r. Perhaps I should just cut my losses and only work with that.
The 35/2.8, though is my least used lens and the worst buy so far for my A7/r systems.

LouisB, my own 35mm 'Cron falls between serial numbers 2,468,501-2,503,100, which means it was made in 1971. I guess it would be called a Type II Pre-ASPH or some such. I posted some image samples from it, and a full size high resolution JPG you can download in my early review of the A7R.
Download the JPG image I shot with this lens, and it should put this whole subject into perfect perspective for you. Decide for yourself with your own eyes how good it is edge to edge, and how well it resolves landscape details, and how good or not the color is. No autofocus, but it has everything else the 55mm f/1.8 has, just in a nice 35mm focal length with some great Leica Mojo. Can you say heaven? It doesn't get any smaller or lighter, and to my eyes I don't think it gets any better.
