Distinguishing itself with an expansive and unique zoom range, the Canon RF 200-800mm f/6.3-9 IS USM Lens from Canon provides superb optical performance while maintaining mobility. Its compact design is complemented by five and half stops of image stabilization to enable strong handheld performance. This lens provides a zoom range that excels in situations where you can’t get closer to your subject without compromising your shot, such as wildlife, nature, and outdoors sports. Swift and nearly silent autofocusing is achieved through Canon’s Nano USM drive system. A focus/control ring and two lens function buttons that are located on the barrel allow for greater control over settings adjustments. Also incorporated are three ultra-low dispersion elements to reduce chromatic and spherical aberrations as well as a Super Spectra coating to minimize ghosting and flare caused by lens surface reflection.  Canon RF 200-800mm USM Lens
