The professional-grade 200-400mm zoom with constant f/4 max aperture and built-in 1.4x extender increases focal length to 560mm for up-close action.
The Image Stabilizer technology enables the use of shutter speeds up to four stops longer than normal without camera shake for great action shots.
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.
Magnesium alloy adds strength and durability, but not weight sealing the lens resistance against dust and moisture no matter your location.
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.
