Hello all I'm fairly new at this and I was looking into buying some lenses for my D200. I am looking at a 50mm f/1.4 D and I have noticed that the going rate for this used, excellent condition is around 250-275 dollars. I was wondering if anyone here knows what is the general cost for a used, excellent condition Nikon AF-S 70-200mm VR f/2.8 G ED-IF? I'm assuming it is out for warranty. Thank you in advance.
