XTI and Weddings

hello, im a newbie here and learning more than i thought from this site. i just bought an XTI and was wondering which lenses would be best for doing wedding photography. i am shadowing a friend who does weddings. i am more or less his gopher.He wants me to take pics that i "see" would be good from someone elses point of view. i've read on here the 24-70 and the 70-200isL as the best choices. would these lenses do good on the XTI? or do you recommend others for this camera? i know people are going to say abetter camera but for now its me and my XTI.

The Wedding Forum FAQ has plenty of info

I'm not at all familiar with the Tamron but the kit lens can produce nice results when stopped down. I would recommend adding a fast prime at some point for low light shooting. You don't have to spend a lot.

Both the 24-70 and the 70-200 are top notch, but I'd recommend small steps first. I got so much more enjoyment out of photography when I learned how to get the images I wanted out of the equipment I have. Take your time and enjoy getting the most out of the gear you have.
