I like it. It's well build and not throughout of plastic! Other L-Lenses also have elements made of plastic. At least the switches. The tube holding the lenses is metal and very solid and feels well in my hand.

You get a lens, which is even protected against dust and it's fast and noiseless. It's worth the money. Sharpness is good, except a little softness in the corners wide open. There also seems to be a few chromatic aberrations sometimes, but they are just slightly visible and marginal. Against the Kit-lens for the 20D, the 18-55 EF-S these aberrations are nothing and not even worth to be mentioned.

Never had problems in 10 months, I would buy it again!
