Overview
Canon RF 45mm f/1.2 STM is a compact, lightweight, and affordable prime lens pairing an extremely fast f/1.2 maximum aperture with a versatile 45mm focal length. Ideal for a walk in the park or a day in the studio, it delivers exceptionally shallow depth of field and beautiful, expressive bokeh.
Thanks to its wide-aperture capabilities and medium focal length, this lens excels for portraits, lifestyle content, and low-light work, producing soft images with dramatic focus falloff. An STM motor affords quiet, smooth autofocus performance with full-time manual focus override. The optical design incorporates one aspherical element to reduce spherical aberrations and distortion.
