This is a late model 'black nose' Olympus OM Zuiko 55mm F1.2 ultra-fast standard lens. It is in good used condition with very light scuffing to the paint on the aperture ring but no dents or dings. The glass is clean and unscratched. It comes with a case (not the original Olympus one), protective (Hoya Pro1 Digital MC UV(O)) UV filter, front and rear caps and a generic (B+W) metal lens-hood.
This lens was designed for use with the acclaimed Olympus OM 35mm SLR film camera system but with widely available adaptors can be used on a range of modern digital cameras. This is an ideal lens for low-light photography, giving a bright viewfinder image on OM system cameras.
