Canon RF 800mm f/5.6 L IS USM Lens

Canon RF 800mm f/5.6 L IS USM Lens

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

High-performance, Wide-aperture 400mm f/2.8 Super-telephoto Lens, Exclusively for EOS R-series cameras

Inheriting the optics of the EF 400mm f/2.8L IS III USM, the same high image quality is maintained in the RF400mm F2.8 L IS USM with outstanding sharpness and contrast, center to corner, even at maximum aperture. A combination of Fluorite and Super UD (Ultra-low Dispersion) glass is at the heart of this lens’s outstanding optical performance. At the widest aperture of f/2.8, chromatic aberration is significantly reduced, to achieve tack-sharp images with minimal color fringing. This means detailed results in any shooting condition, particularly in low light levels.

Optically Identical to EF 400mm f/2.8L IS III USM lens

The latest EF version of the 400mm f/2.8L IS lens, introduced in late 2018, preserved the legendary sharpness of previous EF 400mm f/2.8L lenses, but with a dramatic reduction in overall weight. The RF version, dedicated to EOS R-series cameras, preserves this advantage, providing outstanding handling for a super-telephoto lens with an f/2.8 maximum aperture. Numerous optical and mechanical steps combine for this supremely lightweight, transforming the RF400mm F2.8L IS USM into a lens that’s equally at home in situations requiring mobility and portability — such as motorsports and wildlife — as it is fixed on home plate at a night baseball game. And, since it uses the same optical design as the EF version III lens, the same superb image quality can be expected.

Optical Image Stabilization with up to 5.5 Stops* of Shake Correction, Including Three IS Operation Modes

The RF400mm F2.8 L IS USM features an Optical Image Stabilizer system that provides up to 5.5 stops* of shake correction, delivering consistent and sharp results. Whether hand-held or mounted on a monopod (or other devices allowing mobile positioning), the lens’s Image Stabilization can deliver clear image detail in low-light situations or at lower ISOs. This applies when capturing both stills and video, for stable shooting, and sharp final imagery.

Super Spectra Coating (SSC) and Air Sphere Coating (ASC) Helps Minimize Ghosting and Flare

The RF400mm F2.8 L IS USM lens features Canon's Super Spectra Coating (SSC) that helps maintain overall image quality and color fidelity, as well as Air Sphere Coating (ASC), which significantly helps to reduce the occurrence of lens flare and ghosting. The RF400mm F2.8 L IS USM continues to deliver outstanding images and video, even at maximum aperture, in harsh back-lighting conditions.
