I thought I'd come back and update this thread...
I've been shooting the IIIf for a while now and the one lens that is never out of my little kit bag is the standard 50/2 summicron. I'll occasionally pack the 85 Jupiter but it seems "softish". The 90 elmar is rarely mounted.
I did spring for one of the CV 15mm and the first roll behind THAT lens is AWESOME.
I like the 35 Jupiter, but I'm not shooting it much... I'd like to be able to get closer than it allows me to... maybe a CV in that FL is in the future.
Short version: For people and architecture, I'm getting in close and loving it.
