Used at Super Bowl, bravo Canon
11 February 2014
Summary: I am a professional photographer and just used this lens to shoot the Super Bowl in New Jersey, courtesy our local Canon rep. All I can say is wow. If it weren't for the out-of-reach price tag I would own this lens. For sports, it is almost perfect.
