A professional-grade 200-400mm zoom with a constant f/4 maximum aperture. A built-in extender increases focal length by a factor of 1.4x to 280-560mm.
Image Stabilizer (IS) technology enables the use of shutter speeds up to four stops longer than normal without camera shake. Three IS modes are available, providing effective performance whilst panning and instant stabilisation only during the moment of exposure.
The use of magnesium alloy adds strength and durability, but not weight. The lens is sealed against dust and moisture and the use of fluoride coatings ensures lens elements are easy to clean.
Enjoy fast, near-silent autofocus thanks to a ring-type ultrasonic AF motor. Stay in control with full-time manual focus override, and focus-stop and focus-preset controls on the lens barrel. Power Focus is also available for EOS Movies.
