I have a Canon Xsi and I like the stock lens that came with it, 18-55, but I find I really like to use my 35-135mm lens more. On my list of lens to buy are a 50mm 1.8 (I would love the 1.4) and a nice macro. I like the 35-135 because it give me a nice range of zoom, I guess it is my best all around lens. What is your favorite lens? Why do you like it?
