PLOOT

PLOOT is the designation used by Leitz for an early accessory reflex finder, announced 1934-5,[1][2][3] which adapts one of their screw-mount rangefinder cameras into an approximation of an SLR. The device comprises a mirror, set in the optical path, which directs the image-forming light from the lens upward to a ground-glass focusing screen, with a vertically-mounted viewfinder eyepiece. The mirror is swung up out of the light-path just before exposure, using a double cable-release.[2] The PLOOT is used with telephoto and macro lenses, which are a range made specially for the system, in tubes allowing for the extra depth of the mirror-box on the front of the camera body. For shorter lenses, this extra depth would make focusing to useful distances impossible; however, critical ground-glass focusing is undoubtedly most useful with long lenses.
The PLOOT was superceded by several generations of Visoflex housing.
