Canon RF 400mm f2.8 L IS USM Lens
The Canon RF 400mm f2.8 L IS USM Lens is a world-class, professional super-telephoto prime lens engineered for elite sports, wildlife, and action photography on the Canon EOS R system. As a legendary fixture on the sidelines of global sporting events and in demanding field environments, this L-series masterpiece delivers pristine optical performance, lightning-fast tracking speeds, and robust reliability without compromising on weight distribution.
Key Features
- Ultra-Bright f/2.8 Super-Telephoto Aperture: Provides exceptional light-gathering capability, allowing for fast shutter speeds in low-light environments and creating beautiful, dramatic background separation to isolate distant subjects.
- Up to 5.5 Stops of Optical Image Stabilization: Built-in optical IS counteracts camera shake by up to 5.5 stops (or up to 6.0 coordinated stops on compatible EOS R bodies with IBIS), featuring three specialized IS modes tailored for static subjects, panning, and erratic sports action.
- Dual-Power Ring USM Autofocus Drive: Uses an innovative dual-power ring-type Ultrasonic Motor configuration working alongside high-speed camera communication to ensure blistering, precise, and nearly silent continuous tracking autofocus.
- Fluorite and Super UD Glass Elements: Incorporates two fluorite elements and one Super Ultra-Low Dispersion (UD) element within its optical formula to eliminate chromatic aberration, color fringing, and ghosting for perfect corner-to-corner clarity.
- Air Sphere Coating (ASC) & Super Spectra Coating: Advanced anti-reflective multi-layer coatings drastically suppress internal reflections, minimizing lens flare and maintaining high contrast when shooting directly into stadium lights or harsh sunlight.
- 9-Blade Circular Aperture: Produces exceptionally smooth, rounded out-of-focus highlights and creamy background bokeh that gracefully separates athletes or wildlife from complex backdrops.
- Electronic Manual Focus Control: Offers a customizable electronic focus ring with three selectable manual focus speed ranges, allowing creators to make fine, hyper-precise adjustments during critical tracking scenarios.
- Two Focus Distance Presets: Features a built-in focus preset function that lets photographers store and instantly recall specific focusing distances at the press of a playback button.
- Elite Weather-Proof Architecture: Built to endure extreme professional assignments with extensive dust- and moisture-resistant sealing, alongside a heat-shielding white exterior coating that maintains stable internal optical performance under direct summer sun.
- Fluorine Outer Element Protection: Applied to the front and rear outer lens elements to actively repel oils, water droplets, and fingerprints for fast, scratch-free cleaning on location.
- 52mm Drop-In Filter Holder: Features a rear drop-in filter slot, making it effortless to mount and switch 52mm screw-in filters or optional circular polarizers without removing the massive front lens hood.

Camera System Compatibility
The Canon RF 400mm f2.8 L IS USM Lens provides seamless, native integration across the entire Canon EOS R mirrorless lineup. It pairs optimally with high-performance professional bodies like the EOS R1 and EOS R3 to unlock maximum frame-rate capabilities and cutting-edge deep-learning autofocus tracking tracking tools. It is fully compatible with the Canon RF 1.4x and RF 2x Extenders, instantly transforming the optic into an effective 560mm f/4 or an incredible 800mm f/5.6 super-telephoto lens. When mounted on APS-C format sensors (such as the EOS R7 or EOS R10), it achieves a crop-factored 35mm equivalent focal length of approximately 640mm for extreme reach.
