The 300mm f/6.3 Mirror Lens for Canon EF-M Mount from Bower is a catadioptric lens designed specifically for use on Canon EOS-M mirrorless cameras. The lens' Cassegrain design enables it to achieve a 35mm-equivalent focal length perspective equivalent to 480mm within a compact and lightweight lens design that is significantly smaller than a traditional 300mm lens. It features a fixed f/6.3 aperture and utilizes manual focus operation for focusing as close as 2.95'.

One high index low dispersion element and the inherent mirror construction of the lens work to eliminate chromatic aberrations while providing notable image sharpness and clarity. Furthermore, a multi-coating has been applied to reduce surface reflections, lens flare, and ghosting while also contributing to improved overall contrast.

One high index low dispersion element and a multi-coating are integrated into the lens construction to improve sharpness and clarity as well as reduce aberrations and enhance the overall image contrast.
