The Canon RF 50mm f/1.2L is part of Canon's EOS R system, one of Canon's most important releases since the EOS system began about 30 years ago. To support the optical technologies of this new system, a new mount type RF has been introduced. RF lenses take full advantage of the benefits of a mirrorless design.

Lens and Sensor Distance

The distance between the RF lens' mount and the surface of the EOS R sensor has been reduced from 44mm in the EF/EF-S system to a mere 20mm. Having larger optical elements very close to the sensor means fewer aberrations, greater brightness, and better image performance overall. The number of contact pins has been increased, elevating the speed and volume of communication between the lens and camera. This is supported by a new microprocessor within the lens that increases communication without significantly increasing power consumption. This also allows the EOS R's new Digital Lens Optimizing system to make real-time aberration and distortion corrections over a wide range of shooting conditions and ensures sharpness even when shooting RF lenses at the widest apertures.

Control and Customization

Taking advantage of the communication features listed above, RF lenses provide the unique ability to assign custom shooting functions directly to the lens. A special tactile control ring on the barrel of the lens can be assigned to functions like aperture value, shutter speed, ISO adjustment, and exposure compensation. Rotation clicks give you the sensory cue needed to make these settings changes via the while while composing your shot. You can also can change the direction of manual focus control for the focusing ring.

Significant Bokeh and Brightness

Thanks to the larger mount system, this 50mm can achieve extreme brightness even while maintaining relative portability. It features a wide f/1.2 maximum aperture that produces gorgeous bokeh thanks to the circular 10-blade iris. Subject sharpness is maintained and distortion reduced thanks to special aspheric lens elements. The Air Sphere Coating gives you imagery with clean, aberration-free results that is ideal for controlling flare and ghosting.

The Canon RF 50mm f/1.2L is an innovate prime lens that's an ideal choice for portrait photography as well as street and lifestyle photography. Its superb low light performance and quick speed makes it perfect for weddings and other major events.
