I know they just released the DX18-55 and 55-200 basically to accompany the new D50, which I have purchased. Anyone heard rumors about anything in the 70-300 range specifically for digital cameras, aka DX series? Also, how important is it to have a DX series lens on the D50? Newbie questions from a newbie who is still seeking information about how to maximize a few precious dollars. Several people have suggested that a non-DX lens will mean a lost of digital functionality and quality. Other folks who know quite a bit about the D70 and D50 say that a DX isn't that big of a deal and a non-DX Nikkor 70-300 ED will do fine.
