Canon RF 50mm f1.2 L USM Lens
The Canon RF 50mm f1.2 L USM Lens is a premier, professional-grade normal prime lens built for the Canon EOS R full-frame mirrorless system. As a cornerstone of the prestigious L-series lineup, this lens sets a benchmark for optical resolution, speed, and creative depth-of-field control, delivering stunning sharpness even when shooting wide open at its historic f/1.2 aperture.
Key Features
- Ultra-Bright f/1.2 Aperture: Offers an incredibly wide maximum aperture for unparalleled low-light performance and an extremely shallow depth of field that dramatically isolates subjects.
- Elite L-Series Optical Quality: Engineered with 15 elements in 9 groups to deliver edge-to-edge sharpness, high contrast, and minimal aberration across the entire frame.
- Ring-Type Ultrasonic Motor (USM): Features Canon’s powerful ring-type USM autofocus system to ensure fast, near-silent, and highly accurate focusing for both high-speed tracking and static subjects.
- Advanced Aspherical & UD Elements: Incorporates one Ultra-Low Dispersion (UD) element and three aspherical elements to drastically correct chromatic and spherical aberrations.
- Air Sphere Coating (ASC): Utilizes an advanced anti-reflective coating layer to significantly reduce lens flare and ghosting, maintaining clean contrast in challenging backlit scenarios.
- 10-Blade Circular Aperture: Produces exceptionally smooth, creamy background blur (bokeh) and natural, rounded out-of-focus highlights.
- Customizable Lens Control Ring: Integrates a physical control ring on the lens barrel for direct adjustment of critical settings like aperture, ISO, shutter speed, or exposure compensation.
- Weather-Resistant Professional Build: Dust- and moisture-resistant sealing ensures reliable performance under harsh, demanding environmental conditions on location.
- Fluorine Protective Coating: Applied to the front and rear lens elements to repel water, oil, and smudges, making the outer glass surfaces incredibly easy to clean.
- 0.40m Minimum Focusing Distance: Enables flexible close-up capabilities with a 0.19x maximum magnification factor for detailed creative framing.
- Full-Time Manual Focus Override: Allows immediate, seamless manual focus adjustments at any time, even when the camera is actively operating in autofocus mode.
- High-Speed 12-Pin Communication: Transmits instant data to EOS R-series bodies, optimizing digital lens corrections and maximizing real-time in-body image stabilization.

Camera System Compatibility
The Canon RF 50mm f1.2 L USM Lens is engineered for native compatibility with all Canon EOS R-series mirrorless camera bodies. It pairs optimally with high-resolution full-frame bodies such as the EOS R5 series, EOS R3, EOS R6 series, and EOS R8 to leverage the maximum resolution of the optics. On APS-C sensor camera bodies (like the EOS R7 or EOS R10), it operates with a 35mm equivalent focal length of approximately 80mm, transforming it into an ultra-premium portrait lens with elite low-light performance.
