I've been using a casio p&s camera for a while now and i've finally got the money to upgrade to a dslr. I've done a bit of research and settled on a rebel xt. Now i've been try to find a solid lens, but there are so many to choose from and so many different types. I will be doing photography from the nature side of things. i'm interested in both close up and far away. I'd also like to do some wild life photography too. I'm pretty new to the photography world, so i haven't yet found what i like to photograph the most yet, so i'm looking for a lens that has more of a broad range of function to experience more. The xt will cost me about $390 and i don't want the overall price to go much higher than $800. So if you guys could give me maybe 2 or 3 different lens too look at in my price range, i will go and read some more reviews on them. Any input will be much appreciated. Thanks, Gavin.
