Voigtlander Kontur 35mm

Kontur 35mm

Finder for 24X36 camera 335/36 (1952).
Rare model for 35mm wild angle lens usable on Prominent and Vitessa cameras.
Strange accessory which can be fitted on any camera with an accessory shoe.
This device involves the use of both eyes instead of one,
one eye being applied to the finder and the other looking direct at the subject.
The eye applied to the finder sees simply a sharp, bright rectangle on an opaque black background,
the disengaged eye sees the view and the net result is a bright rectangle superimposed on the view.
