That's my conundrum. Even with noise reduction and tweaking, printed at 8 x 10 the image is too soft. A possible weekend gig earning a few bucks but getting experience means going FX for this kind of gig. Selling the brand new D7100 means also buying at least 1 new lens to replace my 11-16 and 17-55 DX lenses. All my other lenses are FX. Wish this opportunity had come along before I got the D7100, it would have been an easier decision. Then there's the, well, for half again the price of a D600 do I jump in with both feet and get a D800 and have a camera good enough for many years? Not sure what to do.
