www.orphancameras.com 1. LOADING THE BATTERY A. The electronically-controlled shutter will not work without loading the battery. The shutter will be mechanically controlled, without a battery, and will be released at 1/500 sec., regardless of the setting on the shutter speed dial. 4.butkus.org Use one silver oxide battery (EVEREADY No.544 or equivalent). * The battery can be purchased in most photographic supply or electrical appliance stores. B.
2. BATTERY CHECKING If the green-colored battery check lamp lights up when the battery check button is depressed, the battery is loaded properly and there is sufficient power for electronically-con trolled operations. * If the lamp does not light up ( 1 ) the battery is not loaded properly or (2) the battery is completely drained and should be exchanged. A. The film back consists of a film holder and a film back frame, with exclusive film holders supplied for 120 and 220 roll films.
www.orphancameras.com C. Pushing the back cover opening button inwards (in the arrow indicated direction ) opens the back cover and permits the film holder to be detached. D. There are two spool holders on the film holder. The top one is for the fresh film spool while the bottom one is for the empty take-up spool. The left-side shafts of both spool holders can be opened outwards, as illustrated.
E. When the fresh film spool is properly loaded in the top spool holder, draw out the leading end of the film and turn it across the film pressure plate (on the front side of the insert). After running it down to the lower end, turn it over to the empty take-up spool. Insert the leading end of the film into the slit of the take-up spool and wind slightly so that it is securely engaged. * The inside of the leader paper must be facing out, when it is running across the film pressure F.
www.orphancameras.com 4. 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.
6. TIME (T) EXPOSURES A. Time exposures are made with the time exposure lever on the lens, regardless of the setting on the shutter speed scale. B. First, cock the shutter with the film winding crank and then shift the time exposure lever to the left (looking from the body towards the lens), which will expose a red-colored "T" on the barrel. Depress the shutter release button, in this condition, and the shutter will open up. To close the lens shutter.
www.orphancameras.com 7. EXCHANGING LENSES A. THE LENS CANNOT BE DETACHED OR ATTACHED UNLESS THE SHUTTER IS COCKED. Therefore, first, rotate the film winding crank and cock the lens shutter. Next, rotate the milled locking ring on the lens release button 45° in the clockwise direction and then depress the lens release button. Next, while keeping the lens release button depressed, rotate the lens in the clockwise direction, too, until it makes a full stop, at which point it can be detached.
B. To close the focusing hood, first, push down the magnifier (if it is flipped up). Next, press in the side frames, as illustrated, and, at the same time, press the front frame back towards the rear end. The focusing hood will automatically be folded down. * The waist-level finder does not come with the Bronica ETR body and must be ordered separately.) C.
www.orphancameras.com 10. 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 / split-image 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.
12. EXPOSURE COUNTER The exposure counter shows the number of frames exposed or, in other words, is an additive type. Starting from "S", the odd numbers 1, 3, 5, etc., up to 15, are indicated in actual numbers while the even numbers are indicated with dots, coupled with the film winding crank action. The letter "S" and number "15" are orange-colored while the other numbers and dots are white. 13. SHUTTER RELEASE BUTTON A. Depress the shutter release button with the ball of the finger.
www.orphancameras.com 14. DISTANCE SCALE AND DEPTH OF FIELD SCALE A. Distance scales on the Bronica lenses for the ETR can be used for setting the focus on the required distance or finding the distance actually focused. Simply rotate the focusing ring and set the required distance opposite the green 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.
4. Follow instructions enclosed with the infrared film and filter and, to be on the safe side, make several bracketing shots. In general, more exposure rather than less seems to be a safe guide. A. The lens shutter of the Zenza Bronica ETR has a X-setting for flash synchronization, which means that electronic flash units will synchronize at all shutter speed settings, up to the fastest 1/500 second. Thus, it is very convenient for taking shots in daylight which require flash fill-in, too.
www.orphancameras.com The camera body and film back are fully coupled at all times, upon connection. When film backs are interchanged, the shutter cannot be released if the shutter is not cocked or the film is not advanced or both. Upon changing the film back, therefore, always turn the film winding crank completely one time. If the shutter is not cocked or the film is not advanced, the incomplete actions will take place when the film winding crank is rotated. A.
19. INTERCHANGING FINDERS AND MAGNIFIERS A. The waist-lever finder can be exchanged with other optional finders, to match shooting operations to photographic conditions. To detach the finder, simply depress the finder release button, while, at the same time, sliding the finder backwards where it can be detached. B.
www.orphancameras.com A. The focusing screen can be exchanged, depending on the type of photographic work being undertaken. First, remove the finder attached to the camera body. Then, move the screen removal lever in the arrowindicated 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 corresponding openings in the focusing screen frame of the body.
21. 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. 22. ATTACHING AND REMOVING THE NECK STRAP A.
www.orphancameras.com 23. FACTS ABOUT THE BATTERY The battery supplies power for the various electronic control mechanisms incorporated in the Zenza Bronica ETR. 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.
* 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. * See that the left hand does not touch the back cover released button, during photographic sessions, as the back cover may accidentally open and ruin the film. * Restrict cleaning of the reflex mirror to lightly blowing or brushing away the dust and/or dirt with a blower brush or a soft camel hair brush.
www.orphancameras.com 26. ACCESSORIES FOR INCREASING THE VERSATILITY OF THE ETR * Through-the-lens automatic exposure operations, of the aperture-preferred type, are possible, when the exclusive AE Finder is attached to the Zenza Bronica ETR. Exposures are automatically controlled, upon focusing the subject, with brilliantly distinct images captured on the film.
