Fixed Focal Length Lens with High Image Quality and Bright f/1.2 Aperture for the EOS R System
An incredibly bright fixed focal length lens, the RF 50mm F1.2 L USM distinguishes itself by maintaining incredibly high image quality, edge to edge, even wide open at its f/1.2 maximum aperture. With 15 elements in 9 groups and a 10-blade aperture system, it can deliver sharp and detailed images with gorgeous background blur and remarkable consistency.

Minimum Focusing Distance of 1.31 ft/0.40m
Featuring a minimum focusing distance of 1.31 ft./0.40m with a maximum magnification of approx. 0.19x, the RF 50mm F1.2 L USM is capable of sharp and detailed images from nearly any distance. Whether you’re shooting portraits, still life or close ups, the RF 50mm F1.2 L USM can easily provide sharp images with minimal distortion.

Control Ring for Direct Setting Changes
The RF 50mm F1.2 L USM lens incorporates a control ring on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the EOS R camera’s main dial and quick control dial, the control ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback for confident use while looking through the viewfinder. For photographers and moviemakers who would prefer a silent control ring, the clicking mechanism can be removed by a Canon service provider for a fee.

Three Aspherical Elements and One UD Element
Taking advantage of the RF mount, the RF 50mm F1.2 L USM lens offers incredible optical quality and an exceedingly bright f/1.2 maximum aperture. It features 3 aspheric lenses for high image quality from center to corner and a UD lens that helps reduce aberrations for minimized distortion throughout the image plane.

High-speed Communication with the Camera
Designed to quickly process data, the RF 50mm F1.2 L USM features a 12 pin communication system that is the fastest yet for a Canon lens/camera combination. This accelerates AF, Image Stabilization, the Digital Lens Optimizer and more, helping to simplify complex operations and provide a quick and reliable user experience.

Lens Information Display
Another helpful feature, the EOS R camera can display lens information right in the viewfinder, making it easy to confirm the lens’s focal length without looking away from the subject at hand.

In-camera Digital Lens Optimizer
The EOS R system’s 12 pin communication system enables the Digital Lens Optimizer, which works in-camera to combat aberrations and image deterioration, especially in the edges of the image frame when shooting at a large aperture. Data from the RF 50mm F1.2 L USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images.

High Reliability and Durability for Professional Use
Like all L series lenses, the RF 50mm F1.2 L USM lens is built to endure the rigors of professional use. Constructed to be rugged, refined and precise, it can be operated intuitively so concentration can remain on the subject at hand.

Vibration Shock Resistance
Engineered to accommodate its optical system, the RF 50mm F1.2 L USM lens features L series level vibration shock resistance in the lens barrel, helping to maintain focus and settings even in turbulent situations.

Dust- and Water-resistant
For reliable performance even when weather conditions get difficult, the RF 50mm F1.2 L USM lens features dust- and water-resistant construction in the lens mount, switch panel and all rings.

Fluorine Coating
The RF 50mm F1.2 L USM lens features fluorine coatings on the front and rearmost surfaces to help prevent dirt and dust from sticking to the lens, making it easy to clean smudges and fingerprints off.

Air Sphere Coating (ASC) Minimizes Lens Flare and Ghosting
The RF 50mm F1.2 L USM lens features Canon’s Air Sphere Coating (ASC), which significantly reduces the occurrence of lens flare and ghosting regardless of focal length or the angle of light. This helps provide clean results with minimal distractions and aberrations.
