1. Loading the Battery The electronically-controlled speeds of the shutter will not work without loading the battery. One alkaline-manganese or one silver-oxide battery of 6 volts should be used. The shutter will be mechanically controlled when the battery is not loaded, exhausted or when it is loaded with its polarity marks reversed. It will then be released at 1/500 sec, regardless of the setting on the shutter speed dial.
3. Attachment and Removal of Film Back The film back is a film chamber that can be attached or detached freely, this permitting free exchange of film types even during shooting sessions. The camera main body and film back are fully coupled, upon connection. Therefore, always turn the film winding crank completely one time, upon attaching the film back. If winding is not possible, all preparations for taking the picture have been completed.
3. Attachment and Removal of Film Back (con’t) B. To remove the film back from the main body, insert the dark slide into the dark slide slit, as illustrated, with the mark on the dark slide at the top end. Push it all the way in. * There is danger of the film back accidentally becoming detached from the main body, should the dark slide be left in its slit while the camera is being carried. Therefore, make it a rule to withdraw the dark slide promptly upon attaching the film back to the main body. C.
5. Film Loading (con’t) B. Then, the film holder can be detached. C. There are two spool holders on the film holder, with the top for the fresh film spool and the bottom for the take-up spool. The left-side shafts of both can be opened outward, by sliding the spool as illustrated. Insert the right end of the spool on to the rightside fixed shaft and, next, close the left-side holder (shaft) which will engage the spool.
5. Film Loading (con’t) *If the film is not advanced when the film winding crank is rotated, the film holder is not inserted properly and/or the camera main body may be set for multiple exposures. In the latter case, return the multiple exposure lever to an upright or vertical position. (See Section 21: Multiple Exposures) G. Close the back cover, by pressing firmly against the base of the film back, as illustrated.
6. 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 and should prove useful when two or more film backs are used, with different types of films. 7.
9. Film Unloading A. After the 15th exposure of the 120 roll film (30th 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 the 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.
11. Shutter Release Button A. Depress the shutter release button with the ball of the finger. Press all the way in with a smooth and gentle action. * A red-colored LED will flash briefly in the left-rear corner of the focusing screen area, when the shutter is released. This will indicate that the lens shutter has closed and the exposure is complete, and should be noted when using a slow shutter speed. B.
12. Time (T) Exposures The exposures are made with the time exposure lever on the lens, regardless of the setting on the shutter speed scale. However, the lever is locked to prevent accidental movement and must be unlocked for use. A. First, cock the shutter with the film winding crank and then pull up the time exposure lever release.
14. 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 camera main 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. 15.
15. 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 o f -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. 16. Setting the Aperture A.
. Focusing Adjustments The lens is focused on the subject, by rotating the focusing ring in either direction, while checking the effect on the matte surface in the center of the focusing screen. *Various interchangeable Focusing Screen Ei types are available optionally for the camera. Therefore, a type suitable for the photographic work planned should be chosen. (See Section 23: Interchangeable Focusing Screens) 18. Distance Scale and Depth of Field Scale A.
19. Infrared Photography (con’t) 3. After focusing in the normal manner, re-set the distance indicated by the green-colored distance index to the infrared index, by shifting the distance ring. For example, if 5 meters is coincided to the greencolored distance index, when the subject is focused on the focusing screen, then, shift "5" to the red-colored infrared index which will mean that the infrared film is focused at 5 meters. 4.
20. Flash Photography (con’t) To perform TTL automatic flash adjustments on the Zenza Bronica ETRSi, use the SCA300 System Grip Type flash unit and the SCA386 Adapter by connecting. To attach the SCA adapter to the Zenza Bronica ETRSi, follow the instruction shown below. Flash units which can be used: SCA300 System Grip Type flash units. Use the Mounting Bracket in Combinations Attach to the Adapter mounting area of the Mounting Bracket.
22. Mirror Lock-Up A. For photography with the mirror locked up, first cock the shutter with the film winding crank and, then, turn the mirror lock-up lever in the arrow-indicated direction. The lens shutter will be closed down and the reflex mirror and film safety plate will swing up. B. The shutter can be released with the shutter release button or the cable release. * To suspend photography when the mirror is locked up, first, reverse the mirror lock-up lever then rotate the film winding crank.
22. Mirror Lock-Up (con’t) B. Automatic Exposure Operations 1. Align "A" (AE dial) to index mark. 2. Stroke shutter release button on the main body halfway and shutter speed will be displayed in the finder. 3. Lock the mirror up and press the shutter release button fully. * Shutter release should take place as soon as possible after lock-up of the mirror. 23. Interchanging Focusing Screens A. The focusing screen can be exchanged, depending on the type of photographic work being undertaken.
24. Attachment of the Neck Strap A. First, insert the U-shaped ring into the neck strap eyelet, as illustrated. B. Next, insert the U-shaped ring into the slot of plastic ring cover. 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.
25. Facts About the Battery (con’t) Clean the contacts of the battery chamber and the battery with a soft cloth. Don't use sandpaper or emery cloth. The batteries which can be used in the Zenza Bronica ETRSi are the alkaline battery or the silver oxide battery. Both batteries have very good cold weather resistance. However, there is a tendency for performance to drop when the temperature falls below 0° C (32° F).
27. Care and Maintenance (con’t) Clean the plastic focusing screen in the same manner. Don't touch the surface as you may leave fingerprints. Use the silicon-coated cloth, or a soft cloth, to clean the exterior and never use solvents, such as lens cleaning liquid, alcohol or thinner, for this purpose. Use the lens cleaning tissue and very little lens cleaning liquid to clean the lens. Do not use a silicon-coated cloth which can scratch the lens coating.

Film Back Interchangeability One of the greatest attractions of the ETRSi is complete film back interchangeability which makes it possible to detach or attach the film back at any time, in daylight and/or in midroll, and use different film types interchangeably. Thus, an extra film back or two will let a single ETRSi do the work of several, such as, for example: 1.Take color and black-and-white shots of the same subject. 2.
