ok great! these are some good suggestions... i will have to go to the store & take a look at the 1.4 & 1.8 and see where to go from there.

what do you guys think of buying 2nd hand? i found the following ad on kijiji.com, and am interested in having a second body & more lenses, at the great price of $750... any tips when buying 2nd hand? both these lenses will be compatible with my d80, right?
