So I bought a D40 about a month ago and a SB-600 flash, which I've been using and enjoying, however I just found someone selling a D80 locally and can't really figure out if it's worth it or not: D80 w/18-135 lens MB-D80 dual battery pack 67mm UV filter HB-32 shield, cleaning kit, couple memory cards MC-DC1 wired remote All for $650 (I paid about $500 for a D40 w/kit lens + 55-200VR). That seems pretty good to me, especially with the battery pack. So I could try and sell the D40 + kit lens and maybe keep the zoom? Though I guess it doesn't offer me that much more zoom any more, just the VR. So I could sell the D40 stuff and just use that lens for now (with the intent of buying a 50mm prime, as the shooting I've been doing of friends and family generally doesn't require a huge amount of zoom). I honestly haven't gotten super hardcore with the D40 or anything, but there are a few reasons I want to bite: DOF Preview AF lens (the main one really - as I'd like to get a cheaper 1.8 prime and have autofocus) More AF spots I believe the D80 can fire the SB-600 Flash wirelessly More Megapixels - I've done some cropping and this could be of use Any thoughts? Am I stupid for not putting a lot of wear into the D40? Edit: I'm not sure how much it's been used. He claimed his friend, the original owner, hadn't used it too much and he only took about 10 shots with it and realized it was too much camera for him.
