This is a compact and lightweight 800mm super-telephoto lens with enhanced practicality. The excellent optical system includes a UD (Ultra Low Dispersion) lens at the rear end for optimal magnification. The use of fluorite and super UD lenses and other elements delivers clear, sharp, high image quality with no color bleeding. The camera supports high-speed continuous shooting, and burst shooting at a maximum speed of 30 fps*1. The exterior features a thermal barrier coating to prevent the lens body from accumulating heat, when used in the hot sun, as well as a number of focus control functions. In-lens IS provides image stabilization as effective as a 4.5 stop*2 increase in shutter speed. The EXTENDER RF 1.4x and EXTENDER RF 2x can be attached to extend the focal length of the lens by 1.4x and 2x, respectively. These accessories extend the shooting range for a variety of photographic subjects, including wildlife, aircraft, sports, and astronomy.
