Name: Canon RF 28mm f2.8 STM
Brand: Canon

Canon RF 28mm f/2.8 STM is a compact wide-angle lens designed for Canon full-frame mirrorless (MILC) cameras, offering a bright f/2.8 maximum aperture and a featherlight 120 g body.

This versatile Canon RF 28mm f/2.8 STM combines a short 28 mm focal length with a 65° horizontal viewing angle (75° diagonal), making it an excellent choice for landscapes, environmental portraits, and everyday street photography.

Optically the lens uses an 8-element/6-group construction with Super Spectra Coating (SSC) to reduce flare and ghosting, and a circular 7-blade diaphragm to deliver pleasing out-of-focus highlights. The aperture range spans from f/2.8 to f/22.

Autofocus is driven by a quiet STM (stepping motor) AF actuator with full manual-focus override, so you can switch between Auto and Manual focus smoothly for video and stills. The closest focusing distance is just 0.23 m, letting you capture near subjects with attractive background separation.

Physically the lens is small and travel-friendly: 24.7 mm in length, 6.92 cm diameter, a filter thread of 55 mm, and weighing only 120 g. It mounts on Canon RF bayonet interfaces and is finished in a sleek black design; the package includes front and rear lens caps (E-55 and RF) and a user guide.

Note that the lens does not include image stabilization and is not compatible with teleconverters, but it does feature a customizable control ring for exposure or other camera functions. The lens hood model EW-55 is specified but the hood is not included in the box.

Typical use cases include travel photography where light weight matters, wide-angle landscape shots on full-frame bodies, run-and-gun street work, and video production thanks to the smooth STM focusing. The Canon RF 28mm f/2.8 STM offers strong optical performance in a highly portable package, made in Japan and sold as a single-piece boxed unit.
