About the Canon 200-400mm f/4L – EF
The Canon EF 200-400mm f/4L IS II USM 1.4x is a high-magnification, versatile super-telephoto zoom lens featuring integrated Image Stabilizer technology, fast f/4 maximum aperture* and a built in 1.4x extender (*the maximum aperture becomes f/5.6 when the 1.4x range extender is deployed). These features combine to provide an outstandingly versatile lens for professional sports or wildlife photographers as well as broadcast film and television documentary applications.

A robust magnesium alloy design, environmental protection and specialised lens coatings also make it ideal for mobile use, combining with the finest quality optics to deliver exceptional results, even in the most harsh conditions.

Get closer to the action with superior image quality
The reach of the EF 200-400mm f/4L IS USM Extender 1.4x is boosted by its internal 1.4x extender, which is engaged or disengaged at the flick of a lever to provide an extended focal length of 280mm to 560mm – allowing photographers to get even closer to distant action. Ensuring the highest image performance, the optical design includes both fluorite and Ultra-low Dispersion (UD) lens elements, which help minimise chromatic aberration and eliminate colour blurring. Advanced anti-reflection SubWavelength Structure Coating (SWC) and Super Spectra Coating also reduce ghosting and flare. Thanks to the use of the latest optical technologies, image performance is unaffected when the integrated extender is used.

With a fixed f/4¹ aperture the use of high shutter speeds to capture fast-paced action or a low-light scene is possible. A newly designed optical Image Stabilizer, which provides users with a four stop advantage, while IS ‘Mode 3’ applies image stabilisation only at the time of exposure – ensuring that photographers can pan with fast-paced action without IS overcompensating for movement. This feature is ideal for sports photographers, who typically have only a split-second to capture a subject in front of them.

Powerful, flexible focusing
The EF 200-400mm f/4L IS USM Extender 1.4x features Canon’s pioneering ring-type Ultrasonic Motor providing fast, silent autofocusing. For those who prefer to fine-tune focus themselves, full-time manual override allows photographers to manually focus at any moment when using AF. The Power Focus (PF) mode also increases versatility during movie shooting with the EOS-1D C or EOS-1D X, enabling photographers to achieve an accurate pull-focus effect at one of two speeds, simply by twisting the focus recall ring and stopping at a pre-set distance.

High-performance design for professional demands
Designed to answer professional demands for superior image quality and versatile zoom range, the EF 200-400mm f/4L IS USM Extender 1.4x a boasts a premium-quality design befitting Canon’s industry-renowned L-series lenses.

The tough magnesium alloy chassis ensures that, despite the inclusion of the 1.4x extender, the lens is a similar weight to lenses of comparable focal length. Fluorine coatings on the front and rear lens elements also reduce the ability of dirt to cling to the lens surface, while a dust and water-resistant construction allows photographers to shoot in challenging weather conditions. The combination of outstanding optical performance, versatility, weight and tough construction will make it an essential part of any professional sports or wildlife photographer’s kitbag.
