The 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 a 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 outdoor 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. The focus/control ring on the lens barrel can directly adjust shutter speed, aperture, exposure compensation, and other settings. The signature white paint functions as a heat countermeasure when shooting for extended periods under harsh light and works together with the lens’s weather-resistant design to prevent damage from the elements.
