The Canon RF 28mm f/2.8 STM is a remarkably compact and lightweight pancake-style prime lens designed for Canon EOS R full-frame mirrorless cameras. This wide-angle lens delivers everyday 28mm coverage with a bright f/2.8 maximum aperture, making it ideal for travel, street photography, and video work. At just 120g with dimensions of 69.2 x 24.7mm, it is exceptionally portable and unobtrusive, yet features three aspherical elements and Canon Super Spectra Coating for excellent optical performance and minimal ghosting and flare. The STM autofocus motor provides smooth, quiet operation perfect for both stills and video, whilst the 0.23m minimum focusing distance offers versatility for close-up work. Compatible with all Canon EOS R-series cameras, it delivers a 28mm wide-angle perspective on full-frame bodies and an equivalent 45mm coverage on APS-C sensor models.
