Canon RF 1200mm f/8 L IS USM Lens

Canon RF 1200mm f/8 L IS USM Lens

Outstanding Image Quality, 1200mm Super-telephoto Fixed Focal Length Lens

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.
