Zeiss Domnick Super 4x4 prototype

Zeiss prototype camera for 4x4cm exposures on 127 or 227 film, featuring some interesting features like a quick film loading system with two grips on the sides of the body, built-in rangefinder and light meter, bayonet for interchangeable lenses.

Unique T* Sonnar 2.8/60mm no.2592486 in special mount (the lens is indeed included in Zeiss delivery records under the name Domnick!), the camera never went to production and no other prototype is known to exist.
