Alright, I may be asking a lot here but here is my situation. I'm in Iraq now and I'm going to Italy for vacation for 2 weeksion about 17 days. I currently have a Nikon D60 with an 18-200mm 3.5-5.6 VR. I'm not very happy with either. It may be the wheather out here, the dust the sand who knows but the camera is not doing what I want so i'm looking to buy a new camera and lens. I have picked out the D300 and am wanting a 2.8 lens for it. My total budget is about $1900. I have found the camera body for $1500 so that leaves ~$400 for the lens. Is there anything that would be worth it to buy in that price range, for a 2 week trip in Europe?
