I'm starting photography as my new hobby and am in the market for my very first DSLR.
After days of research and reading here at Steve's, I've finally decided to get a Nikon D90 (retracting from a D300 after reading a thread here - I'd rather invest on lenses

I am not sure if i'll be happy if I get the Canon because I really want a Nikon (it just somehow got into me and all the people around me use a Canon.) Problem is, I don't want to spend my hard earned money for that D90 thinking that I can get a D300 with that price!
Anyhow, I also want to know if a Canon lens will fit a Nikon? Or will I be stuck in the future with a Canon if I invest in Canon lenses?
Thanks.
