Title: Limited Life Span
Review: I loved this lens when I first got it, but after about a year of using it, it has peaked. I even sent it back to Canon - and paid over $100 - to have it calibrated and tweaked...and it's just not working right. I certainly used it a lot over the year, but a Canon lens should really perform longer than that. And after sending it back and spending the money to have it "fixed," I'm done spending money on it. The focus is poor and the lens is not durable.
