I have a Summaron 35/3.5 in good condition for my IIIf, and it has produced very nice results for me. Lately, though, I've been reading good things about the f/2.8 version, and have the opportunity to buy one. But I'm still not sure this would be a smart thing to do. Can anyone here tell me if I'd see a big difference switching to the 2.8? I've read through a lot of the past discussions of these lenses on RFF, but haven't been able to find anything comparing the two versions directly.
