Right, I'm having a bit of a dilema about which lenses to purchase with the canon T2i. I had a nikon D40 and feel that it's time to move on to a better camera. Especially because of the video features you get with the T2i. I'm not interested in the kit lens at all. The only definite purchase of mine will be the Canon 50mm 1.8. This could do ok as a walk around lens. I need some ideas about a lens in the range of 70-200mm. Would the Canon 70-200mm f/4.0L be a good idea? Also, taking into mind the 1.6 crop sensor on the T2i. I'm not a beginner photographer but I'm saving a big buy such as the Canon 5D (hopefully Mk3 by then) until I go to university in two years time, maybe then I'll pick up some L glass but for now, I'll want to further my photography and see which areas I prefer. So macrumors, the question is. What lens should I buy with my T2i? Thanks in advance.
