Hello,
I'm new!

I was very fortunate this Christmas to get a new camera. It's a Canon Digital Rebel XT. The little experience I have is mostly with my Canon Powershot S2 IS, so going to a DSLR there are a lot of different things about the camera. I got the kit, and I also received a 75-300 Canon lens. I think I'd like to take it back (75-300), and get a different one (or the same one for less money). I'm not sure about lenses, in what I want, and in what I should probably get. I'll be using my camera for many different things, so I guess what I buy has to be fairly versatile, and is a very good lens for my money, as I am 20 and have no income of any kind. My favorite things to take pictures of are landscapes, and nature, including both wide angle shots and macros, or more accurately, everything under the sun. Also, I don't really know a whole lot on using my new camera too, though I do know a little bit. I'm currently reading the manual, etc. I guess I'm just looking for a bit of help all the way around, in what to do, look at, and maybe some help on some lenses; I'm pretty new to this.
Any help is greatly appreciated; thank you!
Brandon
P.S. If anybody'd like to look at my previous work, please let me know, though don't tell me that I didn't warn you because it was so crappy! :P
