M.Zuiko Digital ED 45mm f/1.8

The Olympus M.Zuiko Digital 45mm f/1.8 is a portrait-length prime lens designed for Micro Four Thirds mirrorless cameras, providing a 90mm equivalent focal length in the 35mm format. The fast f/1.8 maximum aperture enables shallow depth of field for selective focus effects and performs well in low-light conditions. The optical construction features two extra-high refractive index elements that minimize distortion and spherical aberration to deliver sharp, accurate image rendering.

The lens incorporates a Movie & Still Compatible (MSC) autofocus system that provides smooth, quiet, and precise focusing suitable for both photo and video work. A rounded seven-blade diaphragm contributes to pleasing bokeh quality in out-of-focus areas. The compact lens weighs 4.09 ounces and accepts 37mm filters, making it a practical choice for portrait photography and telephoto applications on Micro Four Thirds camera systems.
