I own a D60 that I bought in 2009. I just started a photography program and on the first class my professor (a very nice guy) said 'oh! how nice' in a tone that made me think it was not nice at all. Most of the class is cannon folk and a few other nikons but to them (with higher/newer models) he said stuff like 'oh, that's a GREAT camera!'...Now, I know what matters is the person behind the lens and I know the teacher didn't mean much by it but now I'm thinking if I should upgrade to learn.
For learning purposes, should I upgrade my D60? If so, what would you recommend?
