RF 45mm f/1.2 STM

The Canon RF 45mm f/1.2 STM is a compact prime lens designed for Canon RF-mount full-frame mirrorless cameras with a maximum aperture of f/1.2 and a 45mm focal length. The lens features an STM stepping motor that delivers fast, quiet, and smooth autofocus performance suitable for both video and still photography, with full-time manual focus override available. Its exceptionally fast f/1.2 aperture enables shallow depth of field and expressive bokeh while providing excellent performance in low-light conditions.

The optical design includes one aspherical element that reduces spherical aberrations and distortion for improved sharpness and accurate rendering. The lens measures 3 inches in length and weighs just 12.2 ounces, making it ideal for portable walk-around shooting, studio work, portraiture, and lifestyle photography. A customizable control ring allows for convenient adjustment of focus distance, aperture, or shutter speed depending on user preference.
