Olympus M.ZUIKO Digital 17mm f/1.8 Lens (Black)

The black M.ZUIKO Digital 17mm f/1.8 Lens from Olympus is an all-metal 17mm prime lens designed for the Olympus line of Micro Four Thirds cameras such as the E-PM2, E-PL5 and E-P5 digital cameras. Its focal length is equivalent to 34mm in the 35mm format and its minimum focusing distance is 9.8" (25 cm). It is a very bright, fast lens ideal for everyday photography as well as street photography in which fast shutter speeds and sufficient light is important. Of course, with a wide maximum aperture of f/1.8, this is a fine lens for low-light situations and shallow depth of field imaging.

This lens features Movie and Still Compatible (MSC) autofocus with an inner focus system, which provides fast focusing for stills work and runs smooth and quiet, important when shooting video. The lens barrel has a 'Snapshot' ring which pulls back for manual focus control. Distance and depth-of-field scales for manual control are easily viewable on the lens barrel when the Snapshot ring is pulled back. Three aspherical elements, including a Dual Super Aspherical element to correct aberrations, as well as a High Refractive index element to correct high spherical aberrations, provide quality imaging and ZERO (ZUIKO Extra-low Reflection Optical Coating) lens coatings are applied to the elements to reduce lens flare and ghost images.
