The Canon RF 50mm f1.2L USM is an ultra high speed full-frame prime lens featuring a maximum aperture of f/1.2, allowing for shooting in the lowest of lighting conditions, without needing to resort to shooting with a flash, or unwanted use of high ISO settings. The Canon RF 50mm f/1.2L USM offers a razor thin depth of field, providing fine control over subject isolation, with 10 circular aperture blades to help ensure that out of focus areas are rendered smoothly.
The RF 50mm f1.2L features a ring-type USM (ultrasonic motor) along with optimised focusing algorithms and a high-speed CPU, which use vibrations at an ultrasonic frequency to drive autofocus at an incredibly rapid speed, while maintaining silent operation. Focusing is all internal with no external extension of the lens, with full time manual focusing override available, allowing for delicate focus adjustments if necessary.
The RF 50mm f/1.2L USM features Canon’s new lens control ring offering customisable control over aperture, shutter speed, ISO or exposure compensation. The front filter thread size is 77mm and minimum focusing distance is 40cm.
