The Silver 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 the depth of field for producing selective focus effects. Two extra-high refractive index elements are used to control distortion and spherical aberration for improved sharpness and clarity. Additionally, a Movie and Still Compatible (MSC) autofocus system is employed to deliver quick, quiet, and precise focusing performance to suit both video and photo applications. Its Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
