This lens is a medium to super-telephoto characterized by its fast performance and unique optical design. The rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
Featuring Optical Image Stabilizer
Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure. Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light environments and with slower shutter speeds.
A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to provide fast, precise, and quiet autofocus performance as well as full-time manual focus override. The fluorine-coating on exposed elements affords protection to the optical system, resists fingerprints and smudging, and is easier to clean.
