M.ZUIKO DIGITAL BCL 15mm black

The M.ZUIKO 15mm Body Cap Lens looks like a classic body cap, but is in fact an ultra-short lens with a wide 15mm (30mm equivalent) focal length. Its incredibly compact size - the physical lens width is 9mm - places this lens in the category of versatile wide-angle lenses that you'll always want to have on hand.
You can capture images from a distance of 30cm, giving you a whole new look at the world around you. The lens is equally suited for snapshots. The lens's compact size allows you to use it as a camera body cap, while also enabling you to capture unusual shots in a snap.
