The EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender from Canon 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
specific subject. There is a mode ideal for static subjects, one for
panning with moving subjects and an Exposure Only mode
that applies stabilization only during exposure, offering you the speed
you need to follow fast, erratically moving subjects.
Auto Focusing (AF) is provided by a ring-type Ultrasonic Motor (USM), an
internal focusing system, dedicated AF algorithms and a high-speed CPU.
Full-time manual focus override, 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.
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.
