Canon 50mm f1.2 RF lens

All about EOS RF lenses

Distinguished by its speed, Canon 's RF 50mm f/1.2L USM is a desirable normal-length cousin due to its versatile focal length and bright f/1.2 maximum aperture. This fast design excels in difficult lighting conditions and also benefits work with shallow depth of field and selective focusing techniques. The optical design incorporates a UD element and an aspherical element, which help reduce chromatic and spherical aberrations in order to produce greater clarity and sharpness.

A rounded 10-blade diaphragm also benefits bokeh quality to suit insulating subjects with depth of field. Complementing the imaging capabilities is a suitable annular-type ultrasonic motor, which provides fast, near-silent autofocus and full-time manual focus override. In addition, a unique control ring is integrated into the lens design for intuitive control over lens exposure settings.

• The full-length primary lens is designed for frameless Canon full-frame RF mount digital cameras.
• The exceptionally bright f/1.2 maximum aperture allows extensive control of depth of field for selective focus applications and also benefits working in low-light situations.
• A UD (Ultra Low Dispersion) element is introduced that helps minimize chromatic aberrations and color stripes to provide greater clarity and color accuracy.
• An aspherical element is used to correct spherical aberrations and distortion to improve sharpness and accurate rendering.
• The Ultrasonic Ring Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, accurate and quiet autofocus performance, as well as full-time manual focus override.
• The configurable control ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
• As a member of the esteemed L-series, this lens has a weatherproof design that protects against dust and moisture to allow it to be used in inclement conditions.
• The rounded 10-blade diaphragm contributes to a pleasant bokeh quality.
