My daughter's 15 birthday is coming up and she would like a "real" camera. She has had a auto pocket camera for some time and basically wore it out. I bet she has over 3,000 pictures on her hard drive. So we are looking at either the Canon EOS Digital Rebel or the Nikon digital SLR. I have a few questions: For a 15 year old, how much difference will there be between a 6.1, or a 10.1 or a 12.9 MP camera? In the short term she will probably only put the pictures on her MySpace page, but if I am spending this much money on a good camera I would also like it to last her many years into the future. She has expressed interest on a possible career in photography. I read that the Niko lenses fit the Cannon, but not the other way around. Is this correct? The Nikon can make movies, but the Cannon can't. I am looking for input, so what do you think? Any recommendations?
