Canon RF 50mm f/1.8 STM Lens

Canon's RF 50mm f/1.8 STM is a compact, affordable normal prime for full-frame RF mirrorless bodies, built as an everyday walkaround lens rather than a specialty optic. Its bright f/1.8 maximum aperture works well in dim light and gives real control over depth of field, while one aspherical element cuts spherical aberration and distortion for sharp, accurate rendering. An STM stepping motor gives quiet, smooth autofocus suited to video as much as stills, and a configurable Control Ring on the lens itself lets you adjust ISO, aperture, or exposure compensation without touching the camera body.

• f/1.8 maximum aperture: full-frame RF-mount prime suited to available-light shooting and depth-of-field control.
• One aspherical element: suppresses spherical aberration and distortion for sharp, accurate rendering.
• STM stepping motor autofocus: fast, quiet, and smooth — well suited to video recording as well as stills.
• Configurable Control Ring: adjusts aperture, ISO, or exposure compensation directly from the lens.
• Super Spectra coating: minimizes ghosting and flare for better contrast and color neutrality; 7-blade rounded diaphragm for pleasing bokeh.
