Helen,
You will love your 35 1.2 ; I finally had time to put mine to use in Istanbul 2 weeks ago with some APX 100. Very harsh light so not many occasions to shoot wide open, but I am liking what I see from initial scans. I think it has a fingerprint comparable to the 50/1.5 (which I recall you using very well), but then just a little bit smoother. It size still now and then bothers me, but my initial results are making me care less. Look forward to see your results, I like your shooting style and I think this lens will fit you like a glove. Wish you happy shooting.
