Canon EF 200-400mm f4L IS USM Extender 1.4x

Genuine UK Stock

A professional telephoto zoom suited to photojournalism, wildlife and sports photography

A professional-grade 200-400mm f/4 lens with a built-in 1.4x extender that boosts focal lengths to 280-560mm. A four-stop Image Stabilizer maximises sharpness. Instinctive controls enhance handing.

  • Professional 200-400mm f/4 zoom lens
  • Built-in 1.4x extender
  • Up to four-stop Image Stabilizer
  • Weather-sealed, magnesium-alloy construction
  • Fast USM autofocus with Power Focus for EOS Movies
  • Instinctive focus controls for enhanced handling

    Extendable super-telephoto performance

    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.

    Maximum sharpness whatever the conditions

    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.

    Durable, lightweight construction

    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.

    Quick, intelligent focusing

    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.
