EF 70-200mm f/2.8L USM Is Perfect Complement To EOS System
The new EF 70-200mm f/2.8L USM is a high contrast lens with high resolving
power. It is constructed using the finest optics including four UD (Ultra-Low
Dispersion) glass elements designed for correcting chromatic aberrations,
resulting in extremely sharp images with excellent color rendition.
Designed to maintain a consistent aperture ratio of f/2.8 throughout the zoom
range, the EF 70-200mm f/2.8L USM lens provides photographers with tremendous
shooting latitude. Its fixed aperture throughout its zoom range makes it an
ideal lens for location and sports photographers who have a need for an
assortment of fast lenses but can not afford to weigh themselves down with
excessive gear.
The 70-200mm f/2.8L USM is also the first EF zoom lens that utilizes
tele-extenders. When using the 1.4X or 2X tele-extender, autofocus is
available throughout the entire zoom range of the lens. Manual focusing is
possible when the lens is set in the AF mode.
The new fixed aperture zoom lens incorporates Canon's proprietary Ultrasonic
Motor (USM) lens technology for quiet operation and precise performance. Since
the motor drive unit for the EF lens is in the lens itself, the lens provides
faster AF control and decreases the drive power transmission loss inherent in
lens systems which are driven by motors in the camera body. Further, because
the camera's AF operation is handled within the lens itself, the lens provides
quick, precise operation and high precision start/stop response and
controllability.
