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