Alright, so ive been thinking.... I currently have: Nikon D40x Sigma 10-20mm Sigma 70-200mm Nikon 50mm f/1.8 Ive been trying to build up my kit. Besides that gear i have a fair amount of lighting equipment that i use (strobes, stands, umbrellas...). Ive currently been thinking about upgrading. I have been looking at getting a lens or 2 to cover that area from 20 to 70 and was mainly looking at the sigma 18-50mm f/2.8. I also wanted to get a replacement for the nifty fifty for 2 reasons: 1 i dont like that length, just a little to long, and also, i really am getting tired of mf as most of my shots are of action. So my answer to that was the sigma 30mm f/1.4 (ya, i know, i have a thing for sigma lenses) And after doing all this thinking i was wondering if it would make sense to upgrade my body instead (or aswell). I have like 400 know that i was going to use on next lens (30mm or 18-50) but now im thinking i could sell d40x body and upgrade to something in the likings of a D80 (or better, d200). Opinions?
