Is it too late to exchange the camera for the kit, which comes with a Canon zoom?

I have not ask that particular question. But since I already have the body I thought maybe a better basic lens was the way to go.

HHey there, just found this great forum, my response to your question would be to stay with Cannon lenses, the aftermarket items sometimes do not allow full features from the main camera body, I bought my son a Rebel ( film ) camera and he loves it. Thanks, 710d

I too just bought an XTi and have been reading up on the reviews in various places. The common thread I've found is that the lens that comes with the Rebel XTi is adequate but apparently nothing to write home about. Canon should have included an anti-shake lens with the kit package. Alot of people have reccommended doing exactly what you have done, albeit by accident: Buy the camera body and invest in a decent Canon lens with anti-shake afterwards. Maybe someone here can recommend a good starter lens - I just bought mine (with stock lens) and would be interested in the information as well.
