I'm going to be getting a Canon Digital Rebel XT soon, and I'm wondering if for a noob who is trying to experience all different kinds of photography, it would be better to get this lens or the kit EF-S18-55mm f3.5-5.6 lens bundled with a EF 75-300mm f4.0-5.6 III Canon lens. I really like taking closeup pictures of animals at the zoo, but I'm wondering if maybe it's better to get the better glass, with the IS and USM, and live without the 18-28mm range and the 135-300mm range until I can afford better glass for an ultra wide angle and a telephoto. Does it seem reasonable to go with the better lens but with less range for now? Is it really that much better quality glass? My biggest issue is that I'd really like to do some wide angle and telephoto stuff. Most of what I'm interested in is nature, photojournalism, travel, and animals (at the zoo but maybe some wild depending on where I travel). I have a max budget of less than a grand, including the body, lens(es), a case, cleaning kit, tripod, and memory card.
