well I really wanted the extra stop and a half of lens speed, and thought the CRC would make for better performance throughout the whole focusing range. I am now considering going a cheaper route and getting a 35/2 for low light situations and holding on to the 28/3.5.
It doesn't. Actually it doesn't make a huge differenc closeup, either, at least not on the subjects I use a 28 on (I tried one before I settled on the 3.5 version - not to mention the price difference - the 28 is about the nicest $40 lens I've ever seen ).
I have a 35/2 Nikkor O that I am very happy with, I don't think you'll be dissapointed with that lens.
