Thanks to the RF adapter of the EOS R system, the RF16mm F2.8 STM provides an ultra-wide-angle 16mm focal length while still remaining compact and lightweight, weighing only about 165 grams and only 40.2 mm long. The lens also incorporates a PMo aspherical lens to bring users excellent image quality. Its minimum focusing distance of 0.13 meters and maximum magnification of 0.26x can create close-up images with the unique perspective of wide-angle lenses.
