The C Sonnar T* 1.5/50 ZM lens is the modern technological reincarnation of the classical Sonnar 1.5/50, the fastest standard lens of its time, for the Contax II rangefinder camera. It is fast, very resistant to flaring and unusually compact - therefore the "C" in the lens name.
With its well controlled distortion, the lens produces a very accurate representation of objects. It can take the same filters which fit the ZM wide angle lenses with 28, 25 and 21mm focal lengths. This is a very versatile lens for photojournalistic work in general and for available light photography in particular.
