More details on the Canon RF 50mm f/1.2 L USM

Product Research


Overview: The Canon RF 50mm f/1.2 L USM lens is compatible with the new EOS R series cameras. This standard to medium telephoto lens has an extremely bright f/1.2 aperture and can focus as close as 15.72". It is ideal for capturing portraits, still life, weddings, and many low-light situations.

Lens Construction: The lens is constructed of 15 lens elements in 9 groups. The lens has three aspheric lens elements for high image quality from center to corner, and one UD (Ultra-low Dispersion) lens for reducing aberrations for minimized distortion throughout the image plane.

Lens Coatings: The front and rear lens surfaces are coated with non-stick fluorine to help reduce smears and fingerprints. This helps prevents dust, water, oil, and other surface residue from sticking to the lens, and allows you to quickly and easily wipe the lens clean without the use of solvents. In addition, Air Sphere Coating (ASC) on the lens elements help to combat flare, ghosting, and reflections with reduced aberrations.

Dust- and Water-Resistant: The RF 50mm f/1.2 L USM features dust- and water-resistant construction to provide reliable performance in inclement weather. The lens mount, switch panel, and all rings feature special materials to keep dust and moisture out.

12-pin Communication: The Canon RF-series lenses feature a 12-pin communication system between the camera and the lens (compared to 8 pins for the EF-series). This 12-pin system is the fastest available for a Canon lens and camera combination, and provides faster AF, Digital Lens Optimizer, and more. In addition, the EOS R camera can display lens information directly to the viewfinder, making it easy to confirm the lens' focal length without looking away from your subject.

Control Ring: The RF-series lenses feature a control ring on the lens barrel, which can be assigned to functions that are commonly used on the camera. These functions include shutter speed and aperture settings, or exposure compensation. The ring has a clicking mechanism that acts as a confirmation that the settings are being changed.

Note: The clicking sound could possibly be picked up by the microphone while shooting movies. If you desire a silent control ring, the clicking mechanism can be removed by a Canon service provider (for a fee).

Nano USM: The RF 50mm lens is equipped with Canon's Nano USM (Ultra-Sonic Motor). The Nano USM combines a conventional ring USM and STM (lead-screw type) AF, and features a small chip-shaped ultrasonic motor to give you high-speed, smooth, and precise autofocus and full-time manual focus. The Nano USM operates in near silence, making it ideal for video recording.

Focusing Ring: Regardless of whether the lens is set to manual or auto focus mode, the focusing ring always works. This means you can auto focus on a subject, but manually fine-tune the focus by turning the focusing ring.

Optional Filters: The RF 50mm lens has a 77mm mounting thread on the front of lens for attaching screw-on type filters.

Lens Hood: The lens includes the ES-83 lens hood to keep unwanted light out of the lens, and protects the lens from rain, snow, and dust. You can reverse-mount the lens hood on the lens for storage.

Lens Case: The LP1319 lens case is included for storing the lens when not in use. The case has a drawstring closure at the top.
