The silver M.Zuiko Digital 17mm f/1.8 from Olympus is a 34mm equivalent wide-angle prime for Micro Four Thirds mirrorless cameras. The wide field of view pairs with the bright f/1.8 maximum aperture to benefit working in difficult lighting conditions, and it also offers increased control over the depth of field for working with selective focusing techniques. 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.  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.
