I am a beginner in the photography world (I have worked with a 35mm, but it's been awhile). I have been trying to decide between going with the beginning level XSi or jumping into the more advanced 50D. I will be traveling with this camera on occassion...especially within the next few years...so the main reason I am even looking at the XSi is because of the weight. I am really keen on the control setup on the 50D, but it is a bit heavy...which I feel I would grow accustomed to anyway. I am a small female, but I am pretty strong so I was thinking the 50D won't be too much of a problem. What do you guys think? I am going to the store this coming week to really play around with the two cameras and see what I think of each of them so maybe I can get a better idea that way. I just thought you guys could give me some of the pros and cons (from a users perspective) of each of these cameras. Thanks for your help.
