1. Loading the Battery The electronically controlled shutter will not work without loading the battery. The shutter will be mechanically controlled when the battery is not loaded and will be released at 1/500 sec., regardless of the setting on the shutter speed dial. Use one 6 volt silver oxide battery or alkaline-manganese battery. * The battery may be obtained at any photographic equipment or electrical appliance shop. A.
3.Attachment and Removal of Film Backs If winding is not possible, all preparations for taking pictures have been completed. But, if winding is possible, rotating the film winding crank until it stops will automatically take care of the incomplete action, even if the shutter is uncocked or film is not advanced. Thus, it's always possible to choose the film type most suited for the shot, even midway in the roll.
4. Construction of Film Back A. The film back consists of a film holder and a film back frame, with exclusive film backs available for 120 and 220 roll films. The film holder has an insert or frame for loading film, as well as a built-in winding mechanism. B. The film back frame has a base with a dark slide slit and a back cover with an ASA/ISO film dial and a film type indicator frame.
5. Film Loading (con’t) D. After loading the fresh film spool properly, draw out the leading end of the film and turn it across the film pressure plate (as illustrated). Run it down and turn it over to the take-up spool. Insert the leading end into the slit of the take-up spool and wind slightly until securely engaged. * The inside black surface of the leader must face out when running across the pressure plate, in this case. E.
5. Film Loading (con’t) H. Upon loading the film, rotate the film-winding crank until it stops to place the first frame into place for taking the picture. The exposure counter will also change from "S" to "1", while the shutter will also be cocked. When the film back is detached from the main camera body for film loading, the manual film winder is used for advancing the film. The film will stop when it is in place for the first exposure, with the exposure counter also changing to "1".
7. Film Type Indicator Frame Upon loading the film, tear off the end flap from the empty film package and insert it in the film type indicator frame. This will help you keep track of the film loaded in the film back, even when two or more film backs are used with different films. At the same time, set the film speed with the ASA/ISO film speed dial. This will come in handy when using the finder with built-in exposure meter. 8.
10. Film Unloading A. After the 12th exposure of the 120 roll film (24th exposure of the 220 roll film), the film-winding crank will turn freely with further rotations. Therefore, continue rotating the film-winding crank until the remaining film and all leader paper is wound up on the take-up spool. Open the back cover when winding action becomes very light. B. Remove the film holder and, while preventing the loose film from unwinding, take out the take-up spool.
12. Shutter Release Button A. Depress the shutter release button with the ball of the finger. Use a smooth, gentle action and press all the way in, without using strength or jerking. * A red-colored LED will light up in the front central area of the finder and will indicate that the shutter has closed, in this case. The signal is specially valuable when using slow shutter speeds, as it indicates completion of the exposure. B.
13. Time (T) Exposures (con’t) A. Unscrew the set screw on the time exposure lever until further revolution is impossible, which will permit the lever to be moved freely. * Except for time exposures, always shift the time exposure lever so that "A" is visible on the lens barrel and keep it locked with the set screw to prevent accidental movement. B.
. Interchanging Finders A. 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. Then, gently lower the finder and, when well seated, slide forward until it locks. B. To detach, simply depress the finder release button, while, at the same time, sliding the finder backwards where it can be taken up. 16.
. Waist-Level Finder and Interchanging Magnifiers (con’t) D. The standard magnifier supplied with the waist-level finder has a power of -1.5 diopters, which can be exchanged for others with powers of -4.5, -3.5, -2.5, -0.5, +0.5, and +1.5 diopters. These optional accessories should be purchased to suit the user's eyesight, if necessary. Simply rotate the magnifier frame in the counter-clockwise direction to unscrew. Attach in the reverse manner. 17. Setting the Aperture A.
18. Focusing Adjustments A. 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.
19. Distance Scale and Depth of Field Scale (con’t) These identical pairs of apertures indicate the distance that will be in focus at these lens openings. For example, if the 80mm lens is focused at a distance of 3m, it can be seen from the depth of field scale that the zone will extend from 2 to 7 meters (6 ft. to 23 ft.), when a lens opening of F/22 is used. * See the depth of field table for the Zenzanon-S 80mm lens. 20.
22. Multiple Exposures A. To make up multiple exposures, rotate the film winding crank (to advance the film and cock the shutter) and then turn the multiple exposure lever in the clockwise or arrow-indicated direction, which will expose a red mark. When set in this manner, the shutter can be released and cocked any number of times, without advancing the film. B. Upon taking the multiple-exposed picture, be sure to return the multiple exposure lever back to its vertical position and cover the red mark.
23. Mirror Lock-Up (con’t) D. When S is set to the index with the mirror lock-up switch lever, the lever will automatically return to N, with the next film advancing and shutter cocking action. And, following shots will be normal. E. When C is set to the index with the mirror lock-up switch lever, the lever will not return to N with the next film advancing and shutter cocking action. Therefore, shooting with the mirror locked-up will be possible any number of times.
23. Mirror Lock-Up (con’t) b. Cover the lens and take one blank exposure, as follows: First, return the mirror lock-up switch lever to N setting. Then, use the multiple exposure lever and expose the frame. Finally, after exposing the frame, reverse the multiple exposure lever. (See 22. Multiple Exposures.) c. Utilize film back interchangeability and expose the frame after removing the film back from the main body. Then, continue shooting, according to "b" preceding. (See 3.
25. Attachment of the Neck Strap A. First, insert the U-shaped ring into the neck strap eyelet, as illustrated. B. Next, place the plastic ring cover over the u-shaped ring, as illustrated. C. Next, thread the neck strap through the plastic ring cover (and the U-shaped ring) and pull it out, as illustrated. D. After adjusting the length of the neck strap, pass the leading end of the strap through the buckle, as illustrated, which will fix it securely.
26. Facts about the Battery The battery supplies power for the various electronic control mechanisms incorporated in the Zenza Bronica SQ-A. When used incorrectly, there is a possibility of the wrong exposure being set to the camera and/or the camera not operating. Be sure to use and store the battery correctly for obtaining optimum performance from it at all times. Take the battery out of the battery chamber when storing the camera.
28. Care of the SQ-A Restrict cleaning of the reflex mirror to blowing or brushing with the blower brush or a soft camel hair brush. Don't touch the surface with your fingers or a cloth. Use lens cleaning tissue and liquid to clean the surface of the lens. Do not use silicon-coated cloth for this purpose, as it will prove detrimental to the lens coating. Clean the plastic focusing screen in the same manner. Don't touch the surface as you may leave fingerprints.
