Blue Spectrum Refractive Optics (BR) Reduces Chromatic Aberration
Thanks to our BR optics (Blue Spectrum Refractive Optics), the RF 85mm F1.2 L USM helps capture beautiful detailed photos with minimal chromatic aberration, while also providing stunning resolution.
Minimum Focusing Distance of 2.79 ft./0.85m
With a minimum focusing distance of 2.79 ft./0.85m and a maximum magnification of approx. 0.12x, the RF 85mm F1.2 L USM is capable of capturing sharp and detailed images from various distances. Whether you’re shooting portraits, still life or close ups, the RF 85mm F1.2 L USM can easily provide sharp images with minimal distortion.
Control Ring for Direct Setting Changes
The RF 85mm 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 series cameras’ 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.
One Aspherical Element and One UD Lens
Taking advantage of the RF mount, the RF 85mm F1.2 L USM lens offers incredible optical quality and an exceedingly bright f/1.2 maximum aperture. It features a large diameter Aspherical element for high image quality from center to corner and an Ultra-low Dispersion (UD) glass element that helps reduce aberrations for minimized distortion throughout the image plane.
12 pin Communication System
High-speed Communication with the Camera
Designed to quickly process data, the RF 85mm F1.2 L USM features the 12 pin communication system inherent in all RF lenses. 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
As part of the EOS R system, the RF 85mm F1.2 L USM lens works with an EOS R series camera so that its lens information is displayed 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 85mm F1.2 L USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images.
Dust- and Weather-resistant with Fluorine Coating.
Dust- and Weather-resistant
For reliable performance even when weather conditions get difficult, the RF 85mm F1.2 L USM lens features dust- and weather-resistant construction in the lens mount, switch panel and all rings. Sealing is applied to lens joining sections, and switch panels to help prevent water and dust from entering into the lens.
High Reliability and Durability for Professional Use
Like all L series lenses, the RF 85mm 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 85mm 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.
The RF 85mm 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 off smudges and fingerprints.
Air Sphere Coating (ASC) Minimizes Lens Flare and Ghosting
The RF 85mm F1.2 L USM lens features our 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.
