I don’t have enough knowledge about camera lens. I just bought a new canon camera EOS 50D. I am also planning to buy zoom lens but I have no idea what is the best lens for EOS 50D. Your recommendation is highly appreciated. Thank you.

My brother just bought the Canon EOS Rebel XS (digital)…And I am looking to find one. And I can’t seem to find one on Craigslist. However… I have found tons of Canon EOS Rebel XT (digital). Does anybody know what the difference is? I know I could look it up online… But I want to know from an actual person. So if you know what the difference is or just anything about either of the camera’s please get back to me.

Thank you.
