Hi there, Need some pointers on which Canon/Nikon camera to get. I am a beginner in SLR, but have been using point to shoot cameras for many years. I was told that a professional camera to do catalog taking, would speed up and increase my capacity to do more pictures in a shorter time. My question is how do i know which camera can tether, can't seem to find such information in camera specs (or maybe i just don't know where to look). I appreciate any help on this subject. Thanks.
