Before starting to horizontal and vertical adjustment RF you should know that cameras Zorki, FED have a working piece 28,80mm +/-0,02мм. As the film in a personnel window is curved inside of the camera, the working distance of the camera is established on 0,03-0,005 mm more, than working distance of an objective (28,84 mm). During the installation of a working distance it is not necessary to assort the camera. The working distance of the camera is adjusted by correct installation of a flange (20) Pic.7. It is necessary to adjust paper linings (21) Pic.7 between the camera and a flange (20) to receive working distance . To measure working distance it is necessary to have the special device which you do not have. That is why I'll not begin to explain how it is necessary to do. Before starting adjustment of horizontal and vertical adjustment RF it is necessary to have pliers, a hour tweezers (certainly it is better to have for this purpose a special key, but if you want you can make the key for vertical adjustment by yourself), 2 screw-drivers with width of an edge 1,2 and 2,5 mm. As the beginning I offer you to make the vertical adjustment.
PIC.1
PIC.2
VERTICAL Vertical adjustment of RF is made by a wedge (2) look Pic.1 and Pic.2. It is necessary for you to make the following steps: 1) unscrew chrome plated rim (1) look Pic.1 and Pic.4 which is screwed on the holder (3) very important remark: after having removed chromic rim (1) screw up against the stop a holder (3). 2) Having inserted the ends of a tweezers or a key in the apertures of a frame, a wedge (2) is turned, while both images will not coincide on a vertical one with another. For this purpose it is possible to use drawn on a sheet of a white paper a cross located on distance of 1-2 m from the camera, or a roof of a building on the opposite side of street.
Pic.4
Pic.5
HORIZONTAL Horizontal adjustment of RF is made by the screw (4) look Pic.1, Pic.2 and Pic.15. It is necessary for you to make the following steps: 1) Establish a lens in position ∞. 2) Unscrew with a wide screw-driver the lateral screw 38 Pic.3 and insert a thin screw-driver into a jack for the screw. Easily rotating it, you are to hit in spline of the figured screw (4). Usually screw is being rotated in this or that side depending on position of the second mobile image. If the image does not reach the indefinitely, the screw is screwed up, if passes - unscrewed. It is made until images (motionless and mobile) of the infinite far subject are combined. 3) Check of RF on distance of 2-4 m. For this purpose it is necessary to take a roulette and to measure from a back side of the camera 1, 2 and 4 m and to draw a cross on a sheet of a white paper. After that direct on RF on this sign and check the indications of a scale of distances on a lens. If they are not truthful, RF is not adjusted. In this case it is necessary to unscrew a lens and to continue adjustment of RF, turning a cam (14) Pic.2 no more than on 3-5°. If value on a scale of distances is more than exact, it is necessary to turn a cam upwards. If it is less - downwards. Pic.2 Having turned a cam in the necessary direction on 3-5°, adjust RF again, directing on infinity of the removed subject and on 1 m. It is made until indications of RF on infinity and on 1, 2, 4 m will not accurately coincide with a scale of distances of a lens. Deviations on a scale in 0,5-1mm are supposed at distance up to object of 1, 2 and 4 m, at infinity there should be an absolute coincidence.
