RF1200mm F8 L IS USM Lens

Super Telephoto

Item Code: 5056C002AA


Outstanding Image Quality, 1200mm Super-telephoto Fixed Focal Length Lens Expands the EOS R System.

Optimized magnification optics increase the focal length while retaining nearly the same light weight, portability and high levels of image quality achieved in the RF600mm F4 L IS USM lens. A combination of two large-diameter Fluorite elements, one Super UD (Ultra-low Dispersion) and one UD-glass element provides outstanding sharpness and contrast, even at maximum aperture. A UD lens element positioned in the rear section of the lens provides excellent correction of the increased chromatic aberration generated by the magnification optics. This results in tack-sharp images with minimal color fringing in any shooting condition.

Impressively Light at 7.4 lbs., While Retaining High Levels of Image Quality

Numerous optical and mechanical steps combine to make the RF1200mm F8 L IS USM supremely light weight for its focal length, transforming it into a lens that's equally at home in situations requiring mobility and portability such as when shooting motorsports and wildlife, or if used with a tripod to keep it fixed on a subject such as home plate if shooting at a baseball game. Since it uses the same front-section optical design as the EF version III and RF600mm F4 L-series lenses, similar superb image quality can be expected, delivering visual impact with its amazing telephoto power.

Minimum Focusing Distance of Approx. 14.1 ft. / 4.3 m.

With a minimum focusing distance of approx. 14.1 ft./4.3 m., the RF1200mm F8 L IS USM lens helps you get close to your subjects. At its closest focus distance, users can fill the frame with a subject smaller than a regulation, pro-sized US football.

Optical Image Stabilization with up to 4 Stops* of Shake Correction

The RF1200mm F8 L IS USM features an Optical Image Stabilizer system that provides up to 4 stops* of shake correction, delivering consistent and sharp results. This helps provide reliable monopod-mounted - or even hand-held, for some users -performance and clear image detail in low-light situations or at lower ISOs. This applies when capturing both stills and video, for stable shooting, and sharp final imagery.

Three IS Operation Modes

Three image stabilization modes provide shake-correction for outstanding results in a wide range of shooting situations. These include traditional stabilization, with the correction visible any time IS is active in the camera's viewfinder (IS Mode 1); helping to correct camera shake when intentionally panning horizontally (or vertically), providing shake-correction perpendicular to the photographer's panning movement (IS Mode 2); and stabilization that instantly goes into effect only when the shutter is released - no correction visible between shots, in the camera's viewfinder (IS Mode 3).

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

The RF1200mm F8 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. This helps provide clean results with minimal flare and loss of contrast, especially in heavily back-lit situations.

Compatible with Canon RF1.4x and RF2x Extenders

To help get you even closer to the subject, attach either the optional Canon Extender RF1.4x or Extender RF2x to the RF1200mm F8 L IS USM. Expand effective telephoto power to 1680mm at f/11 with the Extender RF1.4x, or to effective 2400mm at f/16 using the Extender RF2x. Canon RF tele extenders transform the lens into an incredibly powerful telephoto combination for wildlife or sports photography and more.

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

Featuring a customizable electronic manual focus ring on the lens barrel, the RF1200mm F8 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 RF1200mm F8 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.

Two Focus Presets Available - Instantly Return to One or Two Memorized Focus Distances

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. A sports photographer, for example, could easily pre-focus on the midfield line and the goal with the ability to rapidly move focus back to either position with a slight turn of the playback ring on the lens barrel.

9-blade Circular Aperture for Beautiful, Soft Backgrounds

Thanks to its 9-blade, circular aperture, the RF1200mm F8 L IS USM is capable of gorgeous bokeh, achieving 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.

Durable L-series Construction with Dust- and Water-resistant Design, Fluorine Coating on Front Element for Easy Cleaning

Built to L series lens specifications, the RF1200mm F8 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 RF1200mm F8 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.

MTF Charts

A Modulation Transfer Function (MTF) chart measures a lens’ expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens' results from center towards the corners.
