Key Features of the Canon EF 55-200mm f/4.5-5.6 II USM Zoom Lens
Designed for Digital
Same optics as previous EF 55-200mm zoom lens, but new lens coatings to reduce internal reflections when used with digital SLRs.
Superior Optics
Thirteen element design, with front-group focusing.
Revised Electronics
Newly-revised lens CPU and electronics for significantly faster AF with new bodies.
New Exterior Design
New exterior design with ribbed zoom ring and ultra-compact manual focus ring.
Close-Focusing
Close-focusing to 3.9 feet - fill the frame with a subject the size of a postcard.
Circular Aperture
This Canon lens features a new circular apertures diapragm unit, which uses curved aperture blades to provide for a more rounded opening as the lens is stopped down. It's especially effective at rendering out-of-focus background highlights as natural rounded shapes. Offers a more pleasing out-of-focus image.
Ultrasonic Motor
Powered by Canon's exclusive Ultrasonic (USM) motor for autofocusing, the EF 70-200 f/2.8L IS USM is silent in operation and very quick to focus, even in low-light conditions. There is virtually no whining noise as the lens focuses to distract the subject or draw attention to the photographer. Most important for the photographer in the field, the motor draws minimal power so the camera batteries last longer.
EF Lens Mount
In designing the EF lens mount, Canon engineers gave photographers a lot more than simply a way to quickly attach an interchangeable lens to a camera body. With the elimination of mechanical connections and the incorporation of an electronic interface between the camera and lens, Canon cameras have greater flexibility with regard to incorporating future technologies and future system upgrades. This fact has already been proven with a vast increase in AF speed, increased functionality such as predictive autofocus systems found in EOS cameras, auto-aperture tilt-shift (TS-E) lenses, the use of ultrasonic motors and the development of the Image Stabilizer lens.
The fully electronic mount system has none of the shock, operational noise, abrasion, play, lubrication requirements, slow response, diminished precision caused by lever operation, or design restrictions related to linkage mechanisms used to transfer data. Furthermore, operation and reliability are significantly improved. And, a lens operation self-test system, using the lens' built-in microcomputer, can even warn of malfunctions through the camera's LCD readout to help ensure high reliability.
