Hey all, im just starting out and want to make the switch from Digicam to a DSLR. I've narrowed it down to 3 cameras but have no idea which one to get. The Sony a200, Nikon D40X and the front runner, Canon EOS 400D. I was wondering if there are any things that i should know regarding these cameras and suggestions would be great. Thanks!
(I will be using it mostly for architectural, nature, sports and low lighting shots. not sure if this will effect the choice)
