Hi, I'm a graduate student and an intermediate photographer looking to expand my lens collection, mostly so I can 1) continue to bask in the joy of taking beautiful pictures; and 2)begin making a little extra money doing event photography for my academic department and whatnot. For my Digital Rebel, I currently have the 50mm 1.8 II, the 70-200mm 2.8L (my pride and joy, a joint birthday gift from everyone who loves me), and the relatively weak 18-55mm kit lens that came with my camera. I'm looking for a good wide lens, but am having trouble sorting through all the options. Obviously, price is a factor, but I know I'll have the lens forever, and want quality. I've heard some things about the 16-35 L lens that are making me think it might not be worth the money. I'm open to anything anyone might suggest: from a prime to something other than Canon.
THANK YOU so much for your help.
