The M.Zuiko Digital 45mm f/1.8 is a slim, full-frame mirrorless lens that offers an equivalent focal length of 90mm. In addition to offering greater control over depth of field, the short-telephoto focal length paired with a bright aperture offers greater benefit in low light and allows selective focus. Two high-refractive-index elements are incorporated in the lens' optical construction, helping to achieve exceptional sharpness and accurate rendering by reducing distortion and spherical aberrations. In addition, an MSC (Movie & Still Compatible) autofocus system is utilized for both video and photo focusing.

Key Features

  • For better sharpness and clarity, two extra-high refractive index elements are used to control distortion and spherical aberration.
  • A fast maximum aperture of f/1.8 promotes shallow depth of field effects and selective focusing as well as efficiency under poor lighting conditions.
  • It offers a 90mm equivalent focal length for Micro Four Thirds mirrorless cameras.
  • Providing both smooth, quiet, and fast performance, the MSC (Movie & Still Compatible) autofocus system works for both videos and photos.
  • A diaphragm with seven blades contributes to bokeh quality.
