The Canon RF 800mm f/5.6 L IS USM Lens 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.
