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.
