[. . . ] The shutter will stay open when the shutter release button is depressed in this condition. The shutter is closed by shifting the time exposure lever in the opposite direction and exposing the letter "A" once more. 14. Exchanging Lenses The lens cannot be attached or detached unless the shutter is cocked. Therefore, first, rotate the film-winding crank and cock the lens shutter. To attach the lens to the main body, align the orange dot on the main camera body and the red dot on the lens, and then insert the lens fully into its mount. Rotate in the counter-clockwise direction until it stops, with an audible click, which indicates that it is securely locked. B. To detach the lens, the film-winding crank must also be rotated to cock the lens shutter first. Then, press the lens release button down and, at the same time, rotate the lens in the clockwise direction until it makes a full stop. At this point it will be possible to detach the lens. 14 15. The finder can be interchanged, with other optional finders, to match shooting conditions to photographic conditions. To attach the finder, align the front end of the finder with the front end of the finder frame on top of the main camera body, as shown. * If exposure measurements are taken with the depth of field preview lever depressed, when using finders with built-in exposure meters, the shutter speed setting indicated will cause over-exposure. This is because proper exposures are obtained with exposure measurements made at full aperture. 16 18. The lens is focused on the subject by rotating the focusing ring in either direction, while checking the effect on the microprism / splitimage rangefinder spot in the center of the focusing screen (standard type). B. The central split-image spot splits the image into two, with the upper and lower halves separated horizontally when the lens is out of focus. When in focus, however, the two halves will coincide with the displacement disappearing. The microprism ring surrounding the central spot can also be used for checking the sharpness of the focused image, since the image will glitter when the lens is not focused. The surrounding full-area matte surface can also be used for checking image sharpness. 19. Distance Scale and Depth of Field Scale A. Distance scales on the Zenzanon-S lenses can be used for focusing at the required distance actually focused. Simply rotate the focusing ring and set the required distance opposite the orange-colored index, which will adjust the lens for the required distance. B. There is an apparent zone of sharpness, both in front and back of the focused subject, which is known as the depth of field. [. . . ] A red LED will flash above the focusing screen area and signal closing of the shutter when taking the picture. Wait for this signal, especially at slow shutter speeds, before rotating the film winding crank. It should be remembered, when taking pictures, that the final print will not be a square format, especially in the economy size, but will be cut down on both sides or at the top and bottom. 23 28. Care of the SQ-AMM Restrict cleaning of the reflex mirror to blowing or brushing with the blower brush or a soft camel hair brush. [. . . ]
