I just purchased a Canon XT of the internet today. I had been looking for over a month, desiding whether to buy a Nikon D70 or the Canon XT. But I finally bought it! Anyways, thats not the point. Im getting part of the camera as a gift from my parents for my Birthday next week, and it comes with a 50mm f/1.8 lens. Looking on the internet I have seen that this lens gets alot of good reviews, but I also would like to purchase a zoom lens. What should I go with? And are the Tamron lenses as good or better than the Canons? Im pretty new with the DSLRs, I have used SLR film cameras in Photojournalim last semester but thats it. So any advice is appreciated! Thanks!
