ZUIKO 21mm F2 This is the world’s first lens to provide a fast F2 speed in the 21mm focal length. It allows the photographer to focus and frame on a bright viewfinder image, making this lens well suited for photographing dark subjects, for indoor photography and for snap- shooting. True to the OM System design concept, the lens is unusually compact and lightweight.The floating lens group solves the problem of image fall-off at close distances, a frequent difficulty with super wide-angle lenses.
