Equivalent to a 28-135mm lens, this new EF-S lens brings true wide-angle to tele coverage to EOS 60D, EOS 7D and Digital Rebel cameras. It has Canon's Image Stabilization system, allowing safe hand-holding at speeds up to three stops slower than otherwise possible. And of course, it's optically optimized for digital SLRs. A ring-type USM means both fast and silent AF, as well as full-time manual focus when in the AF mode.
Defective design - do not buy
This lens failed when I went to the galapagos. Good thing I had a backup, since having no wide angle would have been a big problem. Came home to find out these lenses are simply bad and wear out. Unreliable autofocus past 18mm means the lens isn't worth much. Buy something else.

I have had this lens for 5 years and before I bought it I was hesitant because of some bad reviews. My copy of the lens has been great. I have never had a problem and the pictures are razor sharp. I use it on a Canon 50D and T2i. It also focuses fast.

Horrible lens! Don't buy!
Lens stopped working during an important photo shoot. The quality is very bad for a Canon lens. Canon needs to recall these lenses and discontinue them. The 15-85mm USM IS is a better option/replacement.

I bought this lens in 2005 when I bought my 20D. I use it as my everyday walk around lens and it has traveled with me around the world. Never a problem. Never a hiccup. The only reason I would change this lens is if they made the same lens in an "L" series. If I can tear myself away from it I am going to send it in to be cleaned so I can use it with my new 7D.
