Relatively sleek despite its super-telephoto reach, the Canon RF 800mm f/5.6 L IS USM is an impressive prime meshing top-of-the-line performance with an updated compact and lightweight design. Ideal for sports, wildlife, and journalism applications, this long lens offers a distinctly tight field of view for isolating distant subjects, along with responsive AF and image stabilization, reliable weather-sealing, and intuitive handling for dependable use in fast-paced situations.

Featuring an optical design based on past EF and RF super-telephoto lenses, this lens features top-range optics designed for the most demanding shooting applications. Two fluorite, one Super Ultra Low-Dispersion (UD), and one UD element virtually eliminate chromatic aberrations for outstanding clarity and color accuracy, void of chromatic aberrations or fringing. Advanced optical design also contributes to the sleeker, more portable form factor of this RF-mount, mirrorless lens. Both Air Sphere and Super Spectra Coatings improve image quality by maintaining high contrast and color accuracy while reducing lens flare and ghosting when working in strong lighting conditions. Rounded nine-blade diaphragm contributes to a smooth bokeh quality.
