The Canon EF 70-300mm f/4-5.6 IS II USM is a flexible zoom well-suited for a variety of subjects, ranging from portraiture to wildlife. Similarly versatile, the lens utilizes NANO USM technology that combines a fast, stills-optimized ring-type Ultrasonic Motor and a smooth, silent video-optimized Stepping Motor for all-around focusing performance to benefit multimedia image-makers. This dual-purpose AF motor also offers notably quicker performance throughout the zoom range for more responsive shooting from near to far. Additionally, also aiding both photo and movie recording, an Image Stabilizer system compensates for up to four stops of camera shake for sharper handheld shooting when working with slower shutter speeds.
