Canon RF 600mm f/4L IS USM Lens

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.

Minimum Focusing Distance of 13.78 ft. / 4.2 m.

At its minimum focusing distance of approx. 13.78 ft. /4.2m, the RF600mm F4 L IS USM can fill the frame with a subject smaller than a regulation, pro-sized US football.

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

Optical Image Stabilization in the RF600mm F4 L IS USM provides up to 5.5 stops* of shake correction, delivering consistent and sharp results. This helps provide reliable handheld — or monopod-mounted — performance and clear image detail in low-light situations or at lower ISOs. This applies when capturing both stills and video for accurate and clear content.

Three IS Operation Modes

There are three Image Stabilization mode settings, for control of shake-correction — each can be applied with the sliding, 3-position switch on the lens barrel. Mode 1 provides general shake-correction for stills and video, with the continuous stabilization correction visible in the electronic viewfinder whenever it’s active. Mode 2 is designed for stabilization when deliberately panning, providing correction for lens/camera movement that’s perpendicular to the photographer’s intentional panning movement. And Mode 3 provides immediate shake correction, but only when the shutter is actually released — so the effect of stabilization is not visible in the viewfinder, between shots.

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

The RF600mm F4 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 regardless of focal length or the angle of light. This helps provide clean results with minimal flare and loss of contrast, especially in heavily back-lit situations.

Customizable Electronic Focus Ring, with Manual Focus Capability during SERVO AF

Featuring a customizable electronic manual focus ring on the lens barrel, the RF600mm F4 L IS USM allows you to select from three different speed levels to adjust manual focus to your desired preference. Adjusted with a 3-position, Manual Focus Speed switch on the lens barrel, Mode 1 provides the “fastest” setting — minimal rotation of the manual focus ring results in significant shifts in actual focus. The Mode 2 and 3 settings add sensitivity, allowing finer focus control as the ring is rotated. The RF600mm F4 L IS USM therefore allows the user to select a preference for quick, rapid manual focus changes, or fine manual focus adjustments.
