Canon RF 85mm f/1.2 L USM Lens

Canon RF 85mm f/1.2 L USM Lens
The Canon RF 85mm f/1.2 L USM is a legendary, professional-grade portrait prime lens engineered natively for full-frame Canon RF-mount mirrorless cameras. Standing as a crown jewel in Canon’s esteemed luxury L-series line, it combines a cherished short-telephoto focal length with an exceptionally bright f/1.2 maximum aperture. Built to achieve absolute optical perfection, this lens delivers staggering wide-open resolution, razor-sharp subject detail, and an otherworldly background bokeh quality. It serves as the definitive workhorse for elite portrait, fashion, wedding, and commercial photographers demanding unmatched low-light performance and peerless depth-of-field control.

Groundbreaking Blue Spectrum Refractive Optics
Elite L-Series Optical Formulation: Specifically engineered to correct the most challenging optical anomalies, producing images with remarkable clarity, contrast, and high-fidelity resolution straight across the frame.

Blue Spectrum Refractive (BR) Optics: Incorporates a specially developed organic BR optical element that virtually eliminates color fringing and chromatic aberrations. By precisely refracting shorter wavelengths of the visible spectrum (blue light), it ensures impeccable color accuracy at high-contrast edges.

Aspherical & Ultra-Low Dispersion (UD) Elements: Features one high-precision aspherical element and one UD glass element to aggressively control geometric distortion, spherical aberrations, and astigmatism, maintaining uniform sharpness at f/1.2.

Air Sphere Coating (ASC): Coated with an advanced anti-reflective ASC layer to eliminate backlit flaring, internal reflections, and ghosting. This technology preserves maximum light transmission and rich contrast, even when shooting directly into harsh sunlight or studio strobes.

9-Blade Rounded Diaphragm: Utilizes a rounded nine-blade aperture configuration to render smooth, circular specular highlights and a creamy out-of-focus background blur.

Exceptionally Bright f/1.2 Speed & Ring-Type USM
Ultra-Bright f/1.2 Maximum Aperture: Affords extensive authority over selective focus techniques, allowing you to isolate subjects against a completely melted backdrop. This extreme light-gathering capability makes it a powerhouse in low available light, allowing for lower ISO values and faster shutter speeds.

High-Speed Ring-Type USM Autofocus: Driven by a powerful ring-type Ultrasonic Motor (USM) paired with an internal focusing design, a high-speed CPU, and optimized tracking algorithms. This ensures blistering, pinpoint, and near-silent autofocus tracking that handles the shallow depth of field with surgical accuracy.

Full-Time Manual Focus Override: Features a large, tactile focus ring that supports immediate manual adjustments at any split second, allowing creators to make fine-grained composition adjustments without leaving autofocus mode.

Weather-Resistant L-Series Build & Custom Control Ring
Configurable Lens Control Ring: Built with Canon’s signature physical control ring on the front barrel. This ring can be mapped via your camera’s internal settings to adjust a variety of exposure parameters directly from the lens itself—including aperture adjustments, ISO sensitivity, shutter speed, or exposure compensation.

Weather-Sealed Professional Chassis: As a member of the esteemed L-series, this housing features extensive dust- and moisture-resistant gaskets at the mount and all structural joints, enabling reliable field deployment in harsh, inclement outdoor conditions.
