Canon RF 800mm f5.6 L IS USM

The Canon RF 800mm f5.6 L IS USM brings super-telephoto reach with the premium quality of the L Series to Canon's R system lineup. 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.

Outstanding Image Quality, 800mm Super-telephoto Fixed Focal Length Lens Expands the EOS R System

Optimized magnification optics increase the focal length while retaining the lightness and high levels of image quality achieved in the EF400mm f/2.8L IS III USM and EF600mm f/4L IS III USM lenses. A combination of two large-diameter Fluorite elements, one Super UD (Ultra-low Dispersion) and one UD-glass element provides outstanding sharpness and contrast, center to corner, even at maximum aperture. A UD lens element positioned in the rear section of the lens provides excellent correction of the increased chromatic aberration generated by the magnification optics. This results in tack-sharp images with minimal color fringing in any shooting condition.

Impressively Light at 6.9 lbs., While Retaining High Levels of Image Quality

The RF800mm F5.6 L IS USM distinguishes itself by maintaining incredibly high image quality expected from a Canon L-series lens with a supremely light weight build for its focal length. This allows for subjects and situations where telephoto power and portability are vital. Since it uses the same optical design in its front section as the EF400mm f/2.8L IS version III lens, similar superb image quality can be expected, delivering visual impact with its amazing telephoto power.

Compatible with Canon RF1.4x and 2x Extenders

To help get you even closer to distant subjects, attach the compatible Extender RF1.4x or Extender RF2x to the RF800mm F5.6 L IS USM. Expand effective telephoto power to 1120mm at f/8 with the Extender RF1.4x, or to an effective 1600mm at f/11 using the Extender RF2x. The extenders allow even more telephoto reach when it’s needed yet allow the user to convert back to an f/5.6 lens for low-light situations by simply removing the extender.

Durable L-series Construction with Dust- and Water-resistant Design, Fluorine Coating on Front Element for Easy Cleaning

Built to L series lens specifications, the RF800mm F5.6 L IS USM features a highly durable design for excellent performance even in inclement weather conditions. It delivers a dust- and water-resistant construction with seals around the mount, switches, rings and more. To help maintain a clean lens, even after multiple lens changes in sub-optimal conditions, the RF800mm F5.6 L IS USM has a specially designed fluorine coating on its front and rear surfaces. The coating helps to prevent water, oil, and other surface residue like fingerprints from sticking to the lens, which facilitates quick and easy wiping, without the use of solvents.
