Leica M3 Betriebskamera with Prototype Telyt 40cm
Betriebskamera with Prototype Telyt
A unique set including a prototype Telyt 8/40cm no.0000048, showing many special features, like the focusing knob that can be moved from the right to the left side, the camera mount that can be rotated 90° for landscape and portrait orientation, the filter slot accepting filters in two different sizes, and the entire lens head equipped with a quick-exchange system (resembling the one on much later Telyt V lenses). It is also one of the first prototype M-mount lenses.
The set also includes an original Leica M3 Betriebskamera no.M3-1149 and a prototype SFTOO 20cm finder, heavily modified with a magnifier built-in on the top, for critical focusing on a Visoflex. Accompanying this unique finder is an original pencil design drawing on parchment dated 17.09.1955.
