What Makes It the Ultimate Telephoto Lens?
-
Unmatched Reach & Detail
With its massive 800mm focal length, this RF lens allows you to shoot from extreme distances without sacrificing image quality. Whether you're photographing rare birds, distant wildlife, or athletes on the field, the Canon RF 800mm f/5.6 L delivers razor-sharp clarity even when your subject is far away.
It’s the ideal Canon RF lens for wildlife and outdoor shooters who need reach without compromise.
-
Superior Optics and Image Stabilisation
Canon packed this lens with premium elements including fluorite and Super UD glass, ensuring minimal distortion and edge-to-edge sharpness. The f/5.6 aperture strikes a perfect balance between speed and control, while the built-in Image Stabilisation (IS) system gives you up to 4.5 stops of shake correction — perfect for handheld or monopod shooting in challenging environments.
This optical excellence sets the standard for what a professional Canon RF lens should deliver in 2025.
-
Pro-Ready Build Quality
Despite its powerful specs, the Canon RF 800mm is surprisingly lightweight and portable. Weighing in at just over 3.1kg, it’s easier to carry and maneuver compared to older EF telephoto options. The build is fully weather-sealed, dust- and moisture-resistant — ideal for fieldwork in any climate.
As part of Canon’s elite L-series lineup, you’re also getting top-tier durability and professional-grade construction built to last.
