So Im upgrading glass instead of my body since someone else paid for my D300 and Im getting the 80-200 f2,8D, and a few other things that will help me light on location. Ill have roughly 400ish bucks left over and I think maybe another lens would be in order. So ... what is the best Nikon lens for 400ish bucks? (I have a 50mm AF-D) I mainly shoot landscapes, portraits, and nature. Also alot of really strange artistic stuff. Opinions? EDIT: Sorry, I also own the 18-200 f/3.5-5.6 VR. I didnt realize I just posted the long end stuff.
