Canon RF 600mm f/4L IS USM lens

Super-telephoto, 600mm Lens with Wide f/4 Maximum Aperture, Exclusively for EOS R-series cameras

The RF 600mm 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 RF 600mm 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, the RF 600mm 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 RF 600mm 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 RF 600mm F4 L IS USM is a great option for professional wildlife photographers.

Compatible with Canon RF 1.4x and 2x Extenders
To help get you even closer to the subject, attach the compatible Extender RF1.4x or Extender RF2x to the RF 600mm 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 RF 600mm 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.

9-blade Circular Aperture for Beautiful Bokeh
Thanks to its 9-blade, circular aperture, the RF 600mm 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.

Dust- and Water-resistant Design, with Fluorine Coating on Front Element for Easy Cleaning
Built to L series lens specifications, the RF 600mm 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 RF 600mm 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.

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

Optical Image Stabilization in the RF 600mm 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.

• [IS Mode 1] Traditional stabilization, with the correction visible any time IS is active in the camera’s viewfinder
• [IS Mode 2] Correcting camera shake when intentionally panning horizontally (or vertically), providing shake-correction perpendicular to the photographer’s panning movement
• [IS Mode 3] Stabilization that instantly goes into effect only when the shutter is released — no correction visible between shots, in the camera’s viewfinder

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

The RF 600mm F4 L IS USM lens features Canon's Super Spectra Coating (SSC) that helps maintain overall image quality and colour 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

The lens’s large manual focus ring is located directly on the lens barrel, and allows you to select from three different manual focus speed levels, to adjust the focus ring rotation to your desired preference. Additionally, depending on camera settings, manual focus is still possible while AF is engaged, letting you fine-tune focus adjustments to suit your shooting preferences.

• [Position 1] The fastest sensitivity (a small amount of focus ring rotation provides significant focus change in the lens)
• [Position 2] Reduced sensitivity for finer adjustments
• [Position 3] Reduced sensitivity for very fine manual focus adjustment

Two Focus Presets Available
Quickly select between one or two memorized focus distances, with focus presets. Especially useful for fixed-position sports photography, you can focus upon and memorize two separate focus distances. Then, with a simple twist of the playback ring, immediately jump back to one or the other.
