CHAPTER I

GENERAL FUNCTIONING Section I. CAMERA BODY

1-1. General Description

The camera body, lenses and accessories supplied with the KS-15(4) Camera Set, together with the LE-11A photographic accessory Kit, is designed for general photographic use. It may be employed in the field, studio or laboratory. It uses 35mm perforated film (black-&-white or color) and mounts interchangeable lenses for wide-angle, normal and telephoto photography. Accessories extend the range to include close-up and photomacrography. The compensating focalplane shutter is self-capping. It is synchronized for flash bulbs at all speeds (1-second to 1/1000-second) and for electronic flash at shutter speeds up to and including 1/50-second. The winding lever simultaneously tensions the shutter, advances the film and actuates the frame counter. The built-in rangefinder couples to interchangeable lenses having focal lengths from 21mm through 135mm, and may be used either as a coincident or split-image type. Bright-line frames, outlining the field, are positioned in the viewfinder when mounting the 35mm, 50mm, 90mm or 135mm f/2.8 lens. Parallax is automatically adjusted while focusing. A delayed action release serves as a self-timer, or for shutter release when using an unsteady support.

Figure 1-1. Shutter Functioning.

The focal plane shutter employs two curtains of rubberized fabric which operate independently of each other. When the shutter is released the first curtain begins its travel across the film aperture and uncovers a portion of the film. At a later interval, determined by the selected shutter speed, the second curtain is released, starts across the aperture and covers the film. The trailing edge of the first curtain.
