I just received my Nikon D80 today! I know it's not top of the line but it's exactly what I need. The lenses that I bought are Sigma's. I know there's alot of dispute with the type of lenses, Nikkor vs. Sigma vs. Tamron. Right now I am trying to familiarize myself with my new baby, trying to figure out what's what and such. One thing I am concerned about is that I live way up north and I would like to know how to take my camera outdoors and safely take pics without ruining my gear. I know I need alot of help with my camera seeing is I am new to digital slr's, please be patient with me.
