Canon RF 50mm f/1.2 L USM Lens
Flagship Professional Normal-Length Prime for EOS R Mirrorless – Ultrafast f/1.2 Maximum Aperture, Ring-Type Ultrasonic Motor (USM) Autofocus System, Customizable Lens Control Ring, Advanced L-Series Optical Formulation (1 UD & 1 Aspherical Element), Circular 10-Blade Diaphragm for Smooth Bokeh, Full-Time Manual Focus Override, Weather-Sealed L-Series Construction, Standard 77mm Filter Thread, Includes Front & Rear Caps and Dedicated Lens Hood (Good Condition)

The Canon RF 50mm f/1.2 L USM is a benchmark professional standard prime lens engineered for full-frame Canon RF-mount mirrorless cameras (also compatible with APS-C EOS R bodies, offering an 80mm equivalent field of view). Renowned for its optical rendering, light-gathering speed, and subject isolation, this optic pairs a natural 50mm perspective with an ultrafast f/1.2 maximum aperture. Designed for commercial portraiture, high-fashion editorial, wedding documentation, low-light street work, and fine-art photography, it yields background separation with subject sharpness across high-resolution image sensors.

The optical formula utilizes 15 elements in 9 groups, incorporating one Ultra-Low Dispersion (UD) glass element and one precision-ground aspherical element to correct chromatic aberrations, spherical distortion, and color fringing wide open at f/1.2. A rounded 10-blade diaphragm produces circular out-of-focus highlights and smooth focus falloff. Autofocus is driven by Canon’s ring-type Ultrasonic Motor (USM) paired with a high-speed CPU and optimized algorithms, delivering swift, quiet, and pinpoint focus acquisition alongside full-time manual focus override. Built to demanding L-series standards, the rugged exterior incorporates Canon’s tactile Lens Control Ring for direct adjustment of exposure compensation, aperture, shutter speed, or ISO, an AF/MF selector switch, a focus limiter switch, comprehensive dust- and moisture-resistant gaskets, and a standard 77mm front filter thread.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: COMPLETE PRIME OUTFIT. Supplied with the Canon RF 50mm f/1.2 L USM lens, Canon 77mm front snap-on lens cap, Canon RF rear dust cap, and authentic Canon ES-83 bayonet lens hood.

Exterior & Physical Status: GOOD CONDITION. The matte black L-series barrel, knurled manual focus ring, tactile control ring, focus limiter switch, red L-series accent ring, bayonet hood mount, and metal RF bayonet flange show moderate, visible signs of standard cosmetic handling and regular use (such as light surface finish marks or rub wear on the barrel/hood). All markings and engravings remain legible and intact.

Optical Status: GOOD TO VERY GOOD CONDITION. Front and rear exterior optical glass surfaces are clean and free of significant scratches, scuffs, haze, or fungus. The internal optical path shows typical minor cosmetic dust settling consistent with normal field use, which does not impact optical rendering, sharpness, or image quality.

Mechanical & Electronic Status: FULLY FUNCTIONAL. The ring-type USM autofocus motor locks quickly, quietly, and accurately; the manual focus ring rotates smoothly; the customizable click-stop Lens Control Ring functions with positive tactile feedback; the circular 10-blade diaphragm actuates reliably across all f-stops; the focus limiter switch and AF/MF switch operate properly; all electronic communications with EOS R camera bodies perform strictly to factory specifications.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Classic 50mm Natural Perspective: Offers a versatile normal field of view mimicking human vision, well suited for environmental portraits, weddings, fashion, and documentary stills.

Ultrafast f/1.2 Maximum Aperture: Provides low-light capability and thin depth of field for background isolation.

Ring-Type Ultrasonic Motor (USM): Delivers rapid, precise, and quiet autofocus performance with full-time mechanical manual focus override.

Advanced L-Series Optical Formulation: Employs 1 UD element and 1 aspherical element to maintain high contrast and sharpness while eliminating color fringing.

Programmable Lens Control Ring: Dedicated barrel ring allows tactile adjustment of exposure settings, including aperture, ISO, or exposure compensation.

Circular 10-Blade Diaphragm: Creates smooth, rounded out-of-focus specular highlights and natural background blur.

Focus Limiter Switch: Allows switching between full focus range and 0.8m-to-infinity for faster AF cycling during distant subject tracking.

Weather-Resistant L-Series Construction: Gasketed throughout the barrel and mount to resist dust and moisture in challenging shooting conditions.

Standard 77mm Filter Thread: Compatible with widely available 77mm screw-on protective, neutral density, and polarizing filters.
