The EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender fromCanon is a high-performance super-telephoto zoom lens with a built-in 1.4x extender that converts the focal range and maximum aperture to 280-560mm f/5.6. The extender is located at the base of the lens and applied with a simple lever switch.
An Image Stabilization system offers up to four shutter speed stops of compensation against camera movement, which is ideal in low-light situations and when shooting at its long focal lengths. Three IS modes are available, each optimized for your shooting subject. There is a mode ideal for static subjects, one for panning with moving subjects and Exposure Only mode that applies stabilization only during exposure, offering you the speed you need to follow fast, erratically moving subjects.
Fast, quiet Auto Focusing (AF) is provided by a ring-type Ultra-Sonic Motor (USM), an internal focusing system, dedicated AF algorithms and a high-speed CPU. Full-time manual focus, which enables the adjustment and fine-tuning of focus even in AF mode, provides precise control over image capture. The Power Focus mode aids focusing during video shooting, allowing the photographer to smoothly adjust focus during filming by twisting the playback ring. Three Focus Limiting Ranges are provided to enable quicker AF in specific situations and AF stop buttons allow you to pause the AF operation if needed. Focus Preset mode allows you to set a focus distance and automatically return to it with just a twist of the playback ring. Focus Preset is available in AF, MF and PF modes.
The EF 200-400mm f/4L IS USM Lens features one Fluorite and four Ultra-low Dispersion optical elements that deliver sharper images with fewer chromatic aberrations. Super-spectra lens coatings minimize ghosting and flare and a Fluorine coating on the front and rear lens elements keep oily smears and fingerprints to a minimum.
A rotatable tripod mount provides stable mounting to monopods or tripods and by loosening its orientation locking knob, the camera can be adjusted to shoot horizontally or vertically without removing it from the tripod. Inside the locking knob is found a security slot for wire-type security locks. Dust and water sealing keeps this reliable L-series lens functioning flawlessly in even the most challenging environments.
In addition to its standard accessories, included with this lens are a monopod mount, lens strap, hard case and case strap.
