Canon RF600mm F4 L IS USM
A lightweight design that completely changes usability, delighting all super-telephoto users. 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. Say hello to action shots with better framing and composition.
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.
Compatible with Canon RF 1.4x and 2x Extenders (Sold Separately)
To help get you even closer to the subject, attach the compatible Extender RF1.4x or Extender RF2x to the RF600mm F4 L IS USM and get the equivalent of 840mm at f/5.6 focal length coverage with the Extender RF1.4x, or 1200mm at f/8 using the Extender RF2x. This added flexibility and versatility helps make the RF600mm F4 L IS USM an amazing option for wildlife photography and more. Canon RF tele extenders transform the lens into an incredibly powerful telephoto combination, with relatively modest additional weight, size and cost.
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. Additionally, manual focus is still possible while autofocus is engaged, letting you fine tune focus adjustments to suit your shooting preferences.
9-blade Circular Aperture for Beautiful Bokeh
Thanks to its 9-blade, circular aperture, the RF600mm F4 L IS USM is capable of gorgeous, evocative out-of-focus areas and soft backgrounds. Delivering more rounded background blur, the 9-blade circular aperture helps create intimacy and intensity in background and foreground bokeh for both photos and videos.
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.
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.
