The black M.Zuiko Digital 17mm f/1.8 from Olympus is a 34mm equivalent wide-angle prime for Micro Four Thirds mirrorless cameras. The optical design makes use of aspherical and high refractive index glass elements to control spherical aberrations and distortion throughout the aperture range for increased sharpness and clarity. Additionally, a Movie & Still Compatible (MSC) autofocus system is employed to deliver quick and quiet focusing performance and a manual focus clutch can be used for more intuitive adjustment and control over focus. Fast f/1.8 maximum aperture helps to achieve shallow depth of field and selective focusing effects, and also benefits working in difficult lighting conditions. Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
