After shooting with my friend's D700 for a good week, I was convinced that it's time to move on to a camera with an FX sensor. So I'm buying a D700, and was looking for a nice mid-range zoom to start off with until I get the money for a 17-35 and 70-200 + a 50mm prime. Particularly, I've been looking at some older AF lenses originally made for film cameras. I'm looking into buying a mint condition AF-n 28-85mm (f/3.5-4.5). Based off of reviews that I've read, it seems like a good starting place until I can afford some better glass. My question is, am I in any way hindering my experience with the D700 by using older film AF lenses? Does anyone have any experience with this lens in particular? Does anyone have any lens suggestions around the same focal length range of comparitive quality/price? Any help is appreciated. Thanks in advance!
