The release of the Canon RF 600mm f/4L IS USM Lens marks the introduction of two new native large aperture super-telephoto lenses for the full-frame mirrorless EOS R system. The RF 600mm f/4L is aimed at professionals and advanced enthusiast photographers capturing wildlife, sports and action, and combines instinctive handling with exceptional results. Image quality is absolutely stunning with Fluorite glass and ASC coatings used in the optical design and the lens offers ultra-fast focusing with up to 5 stops of image stabilisation.
- Large f/4 maximum aperture with 1/8 stop increments for video
- Up to 5 stops of Image Stabilisation (IS)
- Fluorite glass with ASC coatings
- Variable speed manual focusing
- Focus presets with customisable AF start buttons
- Dual Power Focus Drive
- Compatible with RF Extenders
Photographers working with moving subjects benefit from a dual power focus drive, which makes the most of the highly refined Dual Pixel AF system found in Canon cameras. The Canon RF 600mm lens mount features a second power connection, drawing extra power from compatible cameras like the EOS R5. This drives the focusing motor faster, resulting in quicker focusing speed, which lets photographers track faster-moving subjects and gain initial focus even more quickly.
Image results are comparable to the equivalent EF-mount super telephoto lens, in part thanks to the inclusion of 17 optical elements arranged in 13 groups. These include fluorite glass for increased resolution and contrast as well as Canon’s Air Sphere Coating to control ghosting and flare. Users can of course expect competent weather sealing with high durability from this professional quality L-series lens.
Excellent low light performance
The RF 600mm f/4L IS USM delivers impeccably even in poor lighting conditions thanks to a large f/4 aperture and image stabilisation system with up to 5 stops of compensation against camera shake. This will benefit anyone working either indoors or outdoors with less than perfect light as is often the case.
Accomplished focusing performance
A dual powered ring-type USM focus drive is backed up by a high-speed CPU and optimised AF algorithms for quick, quiet focusing. The dual powered focus drive draws extra juice from any compatible camera body to increase the speed of subject acquisition and tracking speeds.
Full-time MF with three manual-focus speeds are available, enabling users to adjust focus instinctively. The barrel also includes customisable AF start buttons, which fall naturally under your finger position, especially useful when shooting video to pull focus.
Smooth bokeh and pin sharp subjects
Canon included a 9-bladed aperture for smooth bokeh and the RF 600mm f/4L IS USM lens incorporates 17 lens elements into 13 groups with sensational results. ASC and Super Spectra coatings result in excellent image control, even when shooting into light sources.
Mount the Extender RF 1.4x or Extender RF 2x for even greater reach up to 1200mm.
