Canon RF Mount. The Canon RF 16mm f/2.8 STM belongs to Canon’s line of RF-mount lenses. It’s compatible with Canon RF-mount cameras, but does not work with Canon EF-mount cameras.

Versatile Ultra-Wide Prime. This lens’s ultra-wide field of view, fast aperture, and compact build make it great for a range of applications, including interior photography, architectural photography, landscape photography, and astrophotography. Its rounded seven-blade diaphragm gives your shots a pleasing bokeh quality, and its bright f/2.8 aperture gives you substantial control over depth of field and lets you work in low light.

Advanced Optical Design. This lens’s seven-group/nine-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. The 5.1-inch minimum focusing distance and 0.26x maximum magnification let you get in close while retaining great depth of field.

Configurable Control Ring. This RF-mount lens features an integrated, configurable control ring that you can use to adjust a range of exposure settings, including ISO, aperture, and exposure compensation.

High-Quality Construction. This lens boasts a weather-resistant build that protects against the elements so you can use it in adverse conditions.
