Been having fun with my rebel xt and the kit lens. I feel it is time to take the next step though and upgrade the lens. Im definatly into landscape photos, especially when hiking. I also have taken a liking to just walking around taking pictures of people/places at school here and whatever animals pop-up. Not sure that a telephoto would be best for anything indoors really but i need a little bit of zoom for mountains/sounds that kinda thing when hiking. I am under the impression that wide angle lens dont have much of a zoom unless you got a lot of money. I am prolly looking at a max of $600 i am willing to spend here seeing that im in school and all. Only idea i have really come up with is the Canon 18-200 f/3.5-5.6 or the 28-135 f/3.5-5.6. These are just what i have found in my short time researching. Im looking for opinions and ideas on what i should do.
