About to order my xti, but i'm not sure what to do with the lens situation. I have already decided on the canon 70-200mm f4 L, but that has taken my budget way down. The reviews on the kit lens aren't too good, so i was contemplating the 50mm 1.8 since its cheap enough with good reviews. I am however worried about the 1.5x crop making it too long as my shortest lens. Suck it up and use the kit lens, or take a step back for a while with better results?
