M 105x1 thread on the front part of the mount serves to screw in the lens hood, light filters or other attachments. A distance scale 1 serves for tentative focusing of the objective lens, when the approximate distance to the object to be photographed is known. The values of the distances are shown on the scale in meters (m) and in feet (ft).   The focusing of the objective is made by rotating the focusing ring 2 that has a decorative covering. The turning ring 3 is used for fastening the objective lens to the stand (for this purpose a seat 4 with 1/4" inched thread is used. Order of operation The installation of the objective to the camera Remove rear lid and make sure that bayonet ring or thread are clean, beforu you install the objective to the camera.

Fastening the objective on the stand  It is recommended to take pictures from the stand, since the objective lens is rather massive. The possibility of swinging the frame through any angle is provided, when taking pictures from the stand. For this purpose slacken the screw 5 a little and swing the lens througt the angle required. Doing this, the objective lens is rotating together with the camera, and the turning ring 3, fastened to the stand remains tripod. Then fix the lens in the turning ring with screw 5. Focusing the objective lens  Focusing is made by rotating the focusing ring 2 till receiving the best sharpness of the photographed object, visible on the focusing screen of the camera. Operating the attachments  Lens hood, that is part of the complete set is used to prevent the beyond-the-frame beams from the bright light sources (the sun, the electric bulb, etc.) to fall on the film. N-4x light filter-neutral, is used to reduce the illumination of the object to be photographed, when there is no other possibility to reduce the quantity of light falling on the film. O-4x light filter-orange, is used when taking pictures of a distant object, for reducing the atmosphere mist, as well as to photograph snow landscapes in sunny weather. The light filter provides the contrast of image: the sky is displayed dark, the clouds are reproduced relief, red hues become distanctly lighter. UV-1,4x light filter- colorless, is used to slacken the influence of ultraviolet rays, which is extremely important when photographing high in the mountains or on the water. It is also used when taking pictures on the color film to eliminate the undesirable effect of ultra-violet rays.
