The 300mm f/6.3 Mirror Lensfor Sony E-mount from Bower is a catadioptric lens designed specifically for use on Sony E-mount mirrorless cameras. The lens' Cassegrain design enables it to achieve a 35mm-equivalent focal length perspective equivalent to 450mm 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.
