I bought a Rebel XTi in September as my first dSLR. Although I've had to get used to the way it exposes (not going into that debate here), I'm very happy with it.
I used to do photography professionally (20 years ago.) I recently photographed a reception for a friend and several people asked me about shooting their receptions. I have never felt comfortable photographing a reception for money without a backup camera. (If the camera goes down, I have no way to fulfill my obligation!)
I almost pulled the trigger on one of the Dell deals on an XTi body but it was just more than I wanted to spend on it.
I've seen several people say they won't get rid of their XT's, despite buying an XTi, because of the XT's great ability to handle ISO 1600. That has me thinking that maybe I should purchase an XT body instead of an XTi. The cost is certainly a lot lower.
Here's what I prefer about the XTi: The larger LCD and I understand the focusing is more accurate than that of the XT. I do shoot some things that would benefit from the better high ISO performance.
Those who own or have owned both, if you didn't currently have an XT would you buy one of those as a backup or would you buy another XTi and why? Also, how hard is it going back and forth between the two. (I have always used identical bodies so that I didn't have to think about the differences.)
Thanks for the opinions.
Michael
