History
Introduction	Fall 2011

The lens has both manual and power zoom (via a rocker switch), useful for smooth zoom motion during videography. Focusing is quiet. The lens has Panasonic's "nano surface coating" for increased contrast and reduced flare. The front of the lens neither extends nor rotates, beneficial for polarized filters. The 46mm thread diameter allows sharing of filters with the Panasonic 14mm, 15mm, 20mm, 25mm, 45mm, Olympus M.Zuiko Digital ED 12mm f/2 and Olympus M.Zuiko Digital 25mm f/1.8 lenses.
