The Canon RF 50mm f/1.8 STM Lens (Canon RF) is a compact, lightweight normal prime that delivers a classic, versatile field of view in an impressively portable design. Ideal for everyday walkaround shooting, portraits, and low-light scenes, this 50mm lens features a bright f/1.8 maximum aperture for strong subject separation and effective depth-of-field control.

A quiet, smooth STM autofocus motor supports video-friendly performance and full-time manual focus override. Completing the design, a customizable Control Ring allows direct adjustment of exposure settings such as ISO, aperture, or exposure compensation—making this lens a versatile, everyday essential for Canon RF shooters.
