The Canon EF 70-300mm f/4-5.6 IS II improves on the original Canon EF 70-300mm f/4-5.6 IS with a faster, stills-optimized Ultrasonic Motor and a silent, video-optimized Stepping Motor making this a great dual-purpose lens. The image stabilization compensates for up to four stops of camera shake when using slow shutter speeds and a unique Lens Information Display mini on-lens Lcd screen reads focus distance, focal length, and your stabilization settings. The Canon EF 70-300mm f/4-5.6 IS II can be paired with both full frame and crop frame sensor cameras. The focal length equivalent on crop frame sensors is 112-480mm. This lens is ideal for wildlife, outdoor sports, ceremonies, and telephoto work for videography.
