This lens was "the" standard lens sold with Yashica SLR cameras. It can be found for low prices, it's very decent. Wide open it's fine for F 1.9, there is a hint of shaded upper edges, but it's perfectly usable. Stopped down it's sharp. The lens has some close focussing capablities. It is relatively small and lightweight, particularly for a F 1.9 lens. A nice lens which offers one usable stop more than a standard lens.
