Equivalent to a 28-135mm lens, this new EF-S lens brings true wide-angle to tele coverage. It has Canon's Image Stabilization system, allowing safe hand-holding at speeds up to three stops slower than otherwise possible. A ring-type USM means both fast and silent AF, as well as full-time manual focus when in the AF mode.


  • Compact, lightweight design with a 5x zoom ratio—28 to 135mm equivalent
  • Excellent optical quality: aspheric element with two aspherical surfaces utilized
  • Close-focusing to 1.15'—at 135mm, fills the frame with subject 3 x 4.4"
  • Ring-type Ultrasonic motor for superior AF performance; allows full-time MF
  • Image Stabilization extends the lens's usefulness in low-light levels
  • Circular aperture design—natural highlights, even stopped down two stops
  • Non-rotating front element; lens length does not change during focusing
  • EF-S lens mount—exclusively for EOS 20D and Digital Rebel bodies
