Whats a good lense for a Rebel XT

The 50 f/1.4 is around $300, while the 50 f/1.8 is around $75. The 1.4 does have a metal mount and is a half stop faster than the 1.8. Either lens would be a great lens to start with, although a little limited indoors by their equivelent focal length of 80mm(just a little long).
setprime is totally correct though when he says the lens is as imortant or more so than the "box"(body) it is attached to, I would say more imortant in every way though. A great lens on a Dreb will blow away a poor lens on a 1D. Garbage in = garbage out, and a photo taken with a poor lens no matter what body will result in a comparitively poor photo.

I can't say enough good things about my EF-S 17-85 IS USM.

28-135 is a good al around lens. Get it with a hood and a UV filter and you'll use it alot.
