Olympus 17mm f/2.8 M.Zuiko Digital
(From Olympus lens literature) The Olympus M.ZUIKO DIGITAL 17mm 1:2.8 Pancake (35mm equivalent focal length: 34mm) lens is even smaller than the already compact pancake lens for Four Thirds bodies. This Micro Four Thirds lens boasts the compactness to the limit with a mere 22mm in length and 71g in weight. The circular aperture diaphragm with 5 blades enables natural and smooth defocusing. This wide-angle pancake lens with its ultra compact design is ideal for daily snapshots and as travel companion.
