I had a pre-ai 35/2.8 and a pre ai 35/2 (which was given to me with a stuck diaphragm. A screw has fallen out, jamming the diaphragm - Nikon's answer was "we no longer service lenses this old".)
Anyway, after fixing the f:2 and comparing them, it seemed that the faster lens had more even illumination, so I traded off the 2.8. I now wish I'd kept both, because the 35/2.8 balances perfectly (along with the 50/2 and 28/3.5) on Nikon F, F2, and Nikkormat bodies.
