・Virtually zero geometric distortion for accurate reproduction of object shapes particularly products and architecture ・Reduces unintended focus shift with aperture variation for improved accuracy of rangefinder defined focus ・Precise 10-blade aperture with 1/3 stop interval click stops ensures exact exposure ・Wear resistant filter mount for long-term reliability in tough conditions ・Highly advanced flare control that ensures crisp brilliant images ・Extremely accurate rangefinder coupling mechanism ensures optical precision contributing to superior image quality
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.
