This question has probably been already tackled a million times, but one the eve of a new purchase I beg for advice. I have a D70. I probably won't go back to film in a 35mm format. I will probably upgrade my camera body in the near future. I need a wide angle zoom (I am a minimalist so I want one lens at that end; I have nothing at that end because I sold my 12-24 DX). My camera store has the 17-55, but not the 17-35. I get the feeling that the market is really excited about the 17-55, but I don't want to pay for hype. I want a good lens that won't go out of style. The price difference between those two lenses doesn't matter to me. I tend to shoot urban landscape/documentary and natural landscape and portraits (for which I obviously have another lens). Which one would you buy, the 17-55 or the 17-35?
