  Achieve maximum sharpness in every condition

  The Image Stabilizer technology enables the use of shutter speeds up to four stops longer than normal without camera shake for great action shots.

• 
  Choose from three Image Stabilizing modes

  The choice of three Image Stabilizing modes provide effective performance whilst panning and instant stabilisation only during the moment of exposure.

Enjoy fast, near-silent autofocus thanks to a ring-type ultrasonic AF motor and never miss the perfect shot.

  Shoot anywhere with its hardy, magnesium-alloy construction

  Magnesium alloy adds strength and durability, but not weight sealing the lens resistance against dust and moisture no matter your location.

  Instinctive controls deliver enhanced handling

  Stay in charge with full-time manual focus override, focus-stop and focus-preset controls on the lens barrel. Power Focus is available for EOS movies.
