My level is absolute beginner and I currently have a Canon XTi with two decent lenses and several low-end lenses. I have experimented with these lenses and do not currently modify my pics for color enhancement. My pics seem drab. Obviously my skill level has tons to do with that but I want to start off with the correct equipment so that I know the results are my skills and not my equipment. I was considering starting over and getting the new Nikon D700 and ONE awesome lens rather than buying one or two prime Canon lenses (70-200 and a 17-55). My goal in the future is to take senior pics and other portraiture photos where color and skin tone are of major importance. The larger format of the D700 is a big motivator. Any thoughts?
