The 1936 Mentorett is a twin-lens reflex made by Goltz & Breutmann/Mentor in Dresden. It takes 120 film and makes 6×6cm negatives. A remarkable feature of the Mentorett (as of the Foth-flex) is the focal plane shutter. Focal plane shutters are uncommon in TLRs. The camera is considered rare[1].
The Mentorett may have two Mentor-Special 7.5cm f/3.5 lenses.[2] Examples have also been seen with Meyer Trioplan lenses.[3][4] The camera is unusual in having iris diaphragms in both the viewing and taking lenses, allowing depth-of-field preview: the two irises are coupled.[5] The shutter has speeds from 1/15 to 1/600s.
Apart from the focal plane shutter, its most significant detail is the lever that serves as film advance lever, shutter cocking device and shutter release in one. With this feature it is possible to shoot rapidly. Its unusual waist level finder is made of leather and protected by a metal hood. The camera has an automatic frame counter. The examples cited also have a galilean viewfinder on the left side of the body.
