I've been carrying pro camera bodies all over the place, but I think that the Rebel XT may be my next camera. I'm a little concerned over the amount of Err99 and other defects, but this camera is so light.
I did a weight comparison between my current camera body (1Ds and 16-35mm) lens, and I would save over two pounds.!!!! That's a 100% savings in weight for a quality camera.
It would be great to have a carry around camera without needing a visit to the masseuse at the end of the day. I've played around with it and I do like. I'm still considering a 20D as my backup camera, but now I have to think about the Rebel XT.
