Hi there!! My dad is a photographer and he bought a Canon two years ago and shortly after that I got my Nikon D50. I LOVE it!! It took one time of my dad using it and he sold his Canon and bought the D50, and has since bought two more higher level Nikon camera's and loves them. We have never had any problems with them.
Go to http://www.steves-digicams.com/
and on the right click on the BEST camera's. THis is a great site. It gives you great comparison phots and imformation. This is where we compared before we bought my Nikon D50. With my Nikon, I got the 18-55 mm and 55-200 mm lenses and love them. Then my dad gave me an extra 18-180 (?) mm (or close to that) and I don't really care for that lense. It doesn't seem to want to cooperate with me. But I have never had a problem with my two lenses that came with it.
