I believe the Leica 35mm f3.5 Elmar is the smallest but the Summaron is technically better (although some may argue). I'm reading up on the optics and all that stuff but size-wise is any of these larger than the other? They look similar but I just wanted to check.
I've used all but the Canon 35/2.8. I had the Canon 35/2, which is a really nice lens, and quite small .. and expensive now, I think.
I would say the Elmar 35 is probably the smallest: it's like a collapsed Elmar 50/3.5 - tiny! I've had a hard time finding one in good condition.
