Canon RF Mount. The Canon RF 50mm f/1.8 STM belongs to Canon’s line of RF-mount lenses. It’s compatible with RF cameras, such as the EOS R5, EOS R6, EOS R, EOS Ra, and EOS RP. It does not work with Canon EF-mount cameras.

Versatile Normal-Length Prime. This lens’s versatile field of view and fast aperture make it great for a range of applications, including vacation photography and general “walking-around” photography. Its rounded seven-blade diaphragm gives your shots a pleasing bokeh quality, and its bright f/1.8 aperture gives you substantial control over depth of field and lets you work in low light.

Advanced Optical Design. This lens’s five-group/six-element optical construction includes a precision-molded aspherical element that helps combat spherical aberrations and distortions for accurate rendering and maximum sharpness. A Super Spectra Coating has been applied to each element to boost contrast and color neutrality, and to minimize ghosting and flare.

Built-In Autofocus. This lens uses a ring-type Stepping Motor to provide fast, accurate, and nearly silent autofocus performance for both still and video shooters. You also get full-time manual-focus override for precision adjustments.
