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 electronic appliance shop. A.
3. Attachment and Removal of Film Backs (con’t) But, if winding is possible, rotating the film winding crank until it stops will automatically take care of the incomplete actions, whether the shutter is not fully cocked or film not fully advanced. Thus, it is always possible to choose the film type most suited for the shot, even midway in the roll. Additional film backs including a Polaroid film back are available optionally in 6 x 6, 6 x 4.5 and 35mm formats.
4. Construction of Film Back The film back consists of a film holder which will be loaded with a roll of film and a film back frame which completely encloses the film holder and shields it from light. * The Film Back SQ/B 120 is for exclusive use of 120 roll film. For loading 220 roll film, use the optional Film Back SQ-I 220. * To take other format pictures such as 6 x 4.5cm, 24 x 35mm, 24 x 54mm or Polaroid pictures, use exclusive film backs. 5. Film Loading A.
5. Film Loading (con’t) D. Rotate the film back winding crank on the right side of the film insert in the direction indicated by the arrow, while checking the advancing film. When the starting point, or arrow mark, is aligned with the triangular start-mark on the top left side of the film insert, stop rotation. E. The starting point, or arrow mark of the unexposed film, can also be aligned with the start-mark, with the film insert loaded in the film back.
5. Film Loading (con’t) H. The manual film winder is used for advancing the film, when the film back s detached from the main body for film loading. The manual film winder can continue to rotate, even when the film is set for the first exposure. It should be rotated 2 or 3 times more, in order to take up any slack in the loaded film. * When loading 220 roll film in the Film Back SQ-I 220, do not mistake the dotted line before the arrow mark for the starting mark. 6.
8. Remarks on Exposure * The Bronica SQ-B does not incorporate an exposure meter. Furthermore, it will not couple with a finder incorporating an exposure meter. * It is possible to attach and view through a finder that incorporates an exposure meter but the meter will not be activated. * It is possible to attach and take photographs with a film back that incorporates an ISO Setting Dial but the ISO setting will not be effective.
11. Setting the Shutter Speed Dial (con’t) * The shutter speed setting can be changed before or after film winding operation. * The shutter is released at 1/500 sec, regardless of the settings when the battery is not loaded, or battery power is insufficient for normal shutter operation. 12. Shutter Release Button Depress the shutter release button with a smooth, gentle action. Do not force or jerk.
. Time (T) Exposure Time exposure is not possible with PS/B 80mm lens supplied with the SQ-B camera kit. When one of the other Zenzanon-PS lenses is attached, time exposures can be made with the time exposure lever on the lens, regardless of the setting on the shutter speed scale. A. First, cock the shutter with the film winding crank and then pull up the time exposure lever lock release. B. Slide the time exposure lever and release the shutter when a redcolored "T" is exposed on the lens barrel.
15. Interchanging Finders A. The waist-level finder can be interchanged with other optional finders to match shooting conditions with 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 sliding the finder backwards at the same time.
16. Waist-Level Finder and Magnifiers (con’t) D. The standard magnifier supplied with the waist-level finder has a power of -1.5 diopters. This 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 a counterclockwise 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 range finder spot in the center of the focusing screen. B. The central split-image spots 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 zone in focus at these lens openings. For example, if the 80mm lens stopped down to f/22, is focused at a distance of 3m (10 ft), the depth-of-field scale shows that the zone will extend from 2 to 7m (7ft to 23ft) at f/22. (See the depth-of-field table for the Zenzanon-PS 80mm lens in section 30.) 20.
22. Multiple Exposures A. To make multiple exposures rotate the film winding crank (to advance the film cock the shutter.) 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 completing a 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 advance and shutter cocking action. All 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 advance and shutter cocking action. Therefore, shooting with the mirror locked up will be possible any number of times.
24. Interchanging Focusing Screens A. The focusing screen can be exchanged, depending on the type of photographic work being undertaken. First, remove the finder attached to the main camera body. Next, move the screen removal levers on both sides in the arrow-indicated directions, as illustrated. Then, using a pair of pincers or a similar tool, lift up the screen with the protrusion at the rear end. B.
26. Attachment of the Neck Strap (con’t) C. After adjusting the length of the neck strap, pass the leading end of the strap through the strap ring, as illustrated. The strap should be fixed securely. * There should be no slack in the strap between the buckle and the plastic ring. 27. Facts about the Battery The battery supplies power for the various electronic control mechanisms incorporated in the Bronica SQ-B.
28. Pointers on Shooting (con’t) The focusing screen is detachable, for exchanging with other types. Do not place trimming masks or tapes on the bottom surface of the screen, as this will lead to inaccurate focusing. 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 the slow shutter speeds, before rotating the film winding crank.
29. Care of the Bronica SQ-B (con’t) If the equipment is not being used for a long period, store everything in tin-lined containers, with plenty of desiccant, such as silica gel. Store the equipment in a cool, dry and well-ventilated (but not windy) place. Do not over tighten when using a longer-than-standard tripod screw, as you may damage the body. Both the main body and lens must be in the "cocked" condition to attach or remove the lens.
