Positioned as the perfect portrait prime, the black M.Zuiko Digital 45mm f/1.8 from Olympus is a sleek 90mm equivalent lens for Micro Four Thirds mirrorless cameras. The short-telephoto focal length pairs with a bright f/1.8 maximum aperture to benefit working in low-light conditions and also offers greater control over depth of field for producing selective focus effects. The optical construction of the lens incorporates two extra-high refractive index elements, which help to reduce distortion and spherical aberrations in order to realise notable sharpness and accurate rendering. Additionally, a Movie & Still Compatible (MSC) autofocus system is employed to deliver quick, quiet, and precise focusing performance to suit both video and photo applications.
