Overview
Capture the action with the RF600mm F4 L IS USM that offers professional and advanced photographers the excellent image quality of a Canon L series super telephoto lens. Ideal for wildlife, motorsports, and more, the RF600mm F4 L IS USM provides up to 5.5 stops* of shake correction, delivering consistent and sharp results. Featuring a customizable electronic manual focus ring on the lens barrel, you can select from three different speed levels to adjust manual focus to your desired preference. Additionally, its f/4 aperture and 9-blade circular aperture helps create intimacy in background and foreground bokeh for both photos and videos, and the lens is highly versatile and lightweight as far as 600mm lenses go, making it easier to not only bring it to the action, but capture it even from a distance. The RF600mm F4 L IS USM makes it easy to bring the action clear and up close.
Super-telephoto, 600mm Lens with Wide f/4 Maximum Aperture, Exclusively for EOS R-series cameras.
With the same optical design as the EF600mm f/4L IS III USM lens, this RF version — dedicated to EOS R-series cameras — brings the same outstanding optical performance to the mirrorless EOS R line. The RF600mm F4 L IS USM distinguishes itself by maintaining incredibly high image quality expected from a Canon L-series lens, with outstanding overall image quality, even at maximum aperture. The Canon 600mm f/4 L-series lenses have historically combined great telephoto power with tremendous sharpness, contrast and clarity, and the RF600mm F4 L IS USM continues that tradition.
Optically Identical to EF 600mm f/4L IS III USM lens
Like the EF600mm f/4L IS III USM lens, introduced in late 2018, the RF600mm F4 L IS USM is highlighted by significant weight reductions, vs. previous-generation Canon 600mm f/4L designs — opening the doors to using this lens for subjects and situations where telephoto power, wide maximum aperture AND portability are vital.  The RF600mm F4 L IS USM will be outstanding for wildlife, birds in flight, motorsports, and similar applications where portability and the ability to quickly move the camera and lens are vital.
Dust- and Water-resistant Design, with Fluorine Coating on Front Element for Easy Cleaning.
Built to L series lens specifications, the RF600mm F4 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 RF600mm F4 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.
Two Focus Presets Available — Instantly Return to One or Two Memorized Focus Distances.
Memorize one — or two — different focus distances, and immediately return to either one with a slight turn of the RF600mm F4 L IS USM len’s playback ring, on the lens barrel. A wildlife photographer, for example, can pre-focus on two different spots where he or she expects wildlife to appear, and immediately jump to either memorized position via the playback ring. Full AF or manual focus operation remains available, as well.
