A lovely example of the Zeiss Ikon Teleskop 1,7x auxiliary teleconverter for Zeiss Ikon Contaflex I and II cameras.

This adapter, which includes the often missing attachment bracket, increases the focal length ot hte standard lens on those Contaflex models to 75mm ( a great portrait length) and does not require exposure compensation.

Excellent used condition. Glass free of scratches, haze, fungus.
