Hey guys, I'm looking for a new lens for my Rebel XT. I already have a 50mm f1.8 and a 28-105mm f3.5-4.5. I'm looking at the wide angle and telephotos for a next one. I've concluded that I need a (maybe super) wide angle zoom first, then a telephoto. For a wide, I really like the Sigma 10-20mm f4.5-5.6. http://www.bhphotovideo.com/bnh/con...s&Q=&sku=381610&is=REG&addedTroughType=search There is also this one: http://www.bhphotovideo.com/bnh/con...669&is=REG&addedTroughType=categoryNavigation ... Then later on (by the end of the summer), I want a telephoto. I really want an L lens, so I was thinking of getting the 70-200mm f4L. http://www.bhphotovideo.com/bnh/con...98&is=GREY&addedTroughType=categoryNavigation I will be shooting mostly photojournalism and the like, as well as general sightseeing, buildings, water bodies and what not. What do you guys think of these lenses, and what other would you suggest (those prices and under, but a little above is okay too)? Thanks so much.
