The local camera shop here has a gorgeous Nikkor 28/2 AiS for $100. I know zip about Nikon lenses but my instinct is to grab it. It's clean and in great shape except a small ding on the filter thread. I would guess it got dropped from a relatively short distance (I didn't notice the ding until the the second time i looked at it and I tend to be pretty careful...meaning it's small) and while it looks like it MIGHT accept a filter I have my doubts. I was actually looking for a 28/2.8 AiS but this popped up. Any thoughts? BTW, the shop has a 7 day return policy as well.
