Zeiss Ikon 5015


Here the text of The Zeiss page and some images:

The powerful photojournalist – fast, compact, accurate

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.

Hi everybody,

Strange that ZEISS is referring to the CONTAX II, because the SONNAR = 1.5 lens ("black") was already delivered for the the CONTAX "I" (not = marked as such!) rangefinder camera in the early 19-thirties !
