The RF800mm F5.6 L IS USM expands the EOS R System for professional and advanced photographers looking for the excellent image quality of a Canon L series super-telephoto lens. Perfect for wildlife, motorsports, and more, the lens feature two large-diameter Fluorite elements, one Super UD (Ultra-low Dispersion) and one UD-glass element, and Air Sphere Coating for outstanding correction of color fringing and superb contrast and sharpness. At an 800mm focal length this lens enables you to achieve incredibly soft backgrounds and tremendous visual impact. Optical image stabilization provides for up to 4.5 stops of shake correction, delivering consistent and sharp results, and at its minimum focus distance, you can fill the frame with a subject as small as a sparrow. It’s compatible with both RF1.4x and RF2x Extenders for even more reach at focal lengths of 1120mm and 1600mm. At an impressively light 6.9 lbs., the RF800mm F5.6 L IS USM is versatile and lightweight making it easy to bring the action clear and up close.
