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 or when it is loaded with its polarity marks reserved. It will then be released at 1/500 sec., regardless of the setting on the shutter speed dial. Your camera is supplied with an alkaline battery. For longer performance we recommend a silver oxide battery (Eveready No. 544, UCAR No. 544 or Duracell No. PX-28.) A.
3. Attachment and Removal of Film Back (con’t) * Make full use of the interchangeable film back. 1. Color and black-and-white in different film speeds can be shot, as required. 2. Continuous shooting is possible if sufficient preloaded film backs are available. 3. Don't waste unsuitable film used in a previous session but simply load up a new film back with the required film type. 4. Many in the studio or at home can use a single ETRS main body, by using additional film backs. A.
4. Construction of Film Back (con’t) B. The film back frame, on the other hand, consists of a base with a dark slide slit and a back cover with a film type indicator frame. The film back frame completely encloses the film holder and shields it from outside light, as well as connecting it to the camera main body. 5. Film Loading A. To open the back cover, squeeze the left and right back cover release buttons, in the arrow-indicated directions, at the same time and the back cover will open. B.
5. Film Loading (con’t) E. Rotate the manual film winder on the right side of the film holder in the arrow-indicated direction, 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 holder, stop rotation. F. The starting point, or arrow mark, can also be aligned with the start-mark, with the film holder loaded in the film back. Simply rotate the film-winding crank on the camera main body, in this case.
5. Film Loading (con’t) When loading 220 roll film in it's exclusive film back, do not mistake the dotted line for the starting point, as it is located before the arrow marks. * See the instructions supplied with Film Back ETRS 135 for proper use of the 135 cartridge loaded film. 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.
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 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. There is no need for strength or jerky action, which will induce camera shake and affect picture sharpness. * A red-colored LED will flash briefly in the left-rear corner of the waist-level finder, when the leaf shutter closes and the shutter action is completed. B.
12. Time (T) Exposure Time 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. Unscrew the set screw on the time exposure lever until further revolution is not possible, which will permit the lever to be moved freely.
. 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.
. 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, 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.
17. Focusing Adjustments A. The lens is focused on the subject, by rotating the focusing ring in either direction, while checking the effect on the micro-prism / splitimage rangefinder spot in the center of the focusing screen (standard type). B. The central split-image spot splits the image diagonally, with the upper and lower halves being separated diagonally when the lens is out of focus. When in focus, however, the two halves will coincide with the diagonal displacement disappearing.
19. Infrared Photography In infrared photography, some adjustments must be made in the focus in order to retain sharpness on the film, because the invisible infrared rays are longer in wavelength than the visible rays used for focusing. For infrared photography: 1. Use an R filter or equivalent with an infrared (black-and-white) film. 2. The red-colored line, next to the green-colored distance index, is the infrared index. 3.
22. 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 camera main body. Then, move the screen removal lever in the arrow-indicated direction, as illustrated. Finally, lift it up by the lever. B. To install the focusing screen, insert the protrusions at the forward end of the focusing screen frame into the corresponding openings in the focusing screen frame of the main body.
23. Attachment of the Neck Strap (con’t) B. Next, insert the U-shaped ring into the slot of plastic 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. Pointers on Shooting Leaving the battery in the camera for a long time, without using it, can lead to leakage problems and result in poor contact. Discard a battery with leakage or corrosion and thoroughly clean out the battery chamber, before inserting a new battery. The shutter cannot be cocked when the film is not loaded in the film back. The use of the multiple exposure lever will, however, permit you to cock the shutter, in such instances.
26. Care and Maintenance (con’t) Always protect the lens with its cover when carrying the camera. Clean the camera and lens carefully after using it outdoors in wet weather or at the seashore. Wipe the camera carefully with a well-wrung damp cloth, using fresh water, if the exterior is affected by salty air. Then, wipe it dry with a soft, dry cloth. If necessary, send it out for a quick inspection at an authorized repair station.

Automatic Close-Up Photography Automatic Close-up Photography Automatic close-up photography is possible with the ETRS, which makes close-up shooting very simple, contrary to the difficulties and limitations normally encountered when taking close-up shots. Automatic Bellows Attachment E The accessory provides variable lens extensions continuously with Zenzanon-E lenses from 40mm to 250mm, with the lens shutter and lens diaphragm actions automatically coupled to the control circuit, upon attachment.
