I'm a complete noob to the photography scene. The two cameras listed in the title are the ones that have caught my eye first. The problem I'm having is the P80 has a higher megapixel and zoom feature but is not SLR whatever that is. The D40 seems to be the cheapest Nikon SLR camera but it only has a megapixel rating of 6.1. Can someone tell me if I choose the D40 will I loose picture quality and if it were you which one would you go with and why. As always thanks in advance for any advice.
