Tamron BRONICA ETRS Owner Manual

Congratulations on your choice of the Zenza Bronica ETRS single lens reflex camera, which will offer you high quality performance, handling convenience and versatility required for professional photography. The Zenza Bronica ETRS has been developed as a "system" camera, with a very high degree of interchangeability. The Zenza Bronica ETRS is backed up by a full range of valuable accessories, which permit use in many other day-to-day assignments, which require a fast-handling camera with complete exposure automation. Although instructions described in this booklet are based on a standard combination consisting of the ETRS main camera body with standard Zenzanon-EII 75mm lens, Film Back ETRS 120 and Waist-level finder E, these lenses,film back and finder are left to your discretion to select such items best suited for your picture taking.To get best results from your camera, we suggest that you read this instruction manual carefully, before you even touch the camera.

Film type indicator frame

A. Depress the battery chamber button with your finger and at the same time, move the battery chamber cover in the arrow-indicated direction. The cover will come off easily.

B. Coincide the plus (+) and minus (-) marks on the battery with similar polarity indications in the battery chamber. Then, push the negative end of the battery first and follow with the positive end. Insert the BATTERY end of the battery chamber cover, which also has a mark coinciding to that on the body. Then move the cover in the other direction (opposite to the arrow indication) until it locks in place.

If a red colored LED lights up in the left-rear corner (of the waist-level finder) when the battery check button is pressed, the battery is loaded properly and there is sufficient power for electronic operations.

* If the LED does not light up, (1) the battery is not loaded properly or (2) it is completely drained.

The film back is a film chamber that can be attached or detached freely, thus 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 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, whether un-cocked shutter or film not advanced.Thus, it's always possible to choose the film type most suited for the shot, even midway in the roll.

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.)

2. Battery Checking

3. Attachment and Removal of Film Back

* 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.

C. Depress the film back release button and the lower end of the film back can be removed, as illustrated. Simply shift the film back up slightly and pull it away.

* The dark slide can be withdrawn, even while the film back is detached from the main body and, therefore, extra care is required, in this respect.

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.

A. To attach the film back to the main body, simply insert the latches at the upper end of the film back into the attachment openings at the upper end of the main body. Then, press the lower end of the film back against the main body until it locks securely.

* The dark slide must be withdrawn from its slit, upon attachment of the film back to the main body, as otherwise the shutter cannot be released.

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. The film holder has an insert or frame for loading film, as well as a built-in film winding mechanism.

3. Attachment and Removal of Film Back (con’t)

4. Construction of Film Back

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.

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. Then, the film holder can be detached.

C. 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 outward, as illustrated. Therefore, insert the right end on the spool on to the right-side shaft, which is fixed, and then close the left-side holder (shaft), which will engage the spool.

* The spool holders on the left side will be locked securely, when the back cover is closed.

5. Film Loading

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. 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. This method is preferred since there will be coupling with the camera main body mechanism, from the beginning.

G. Close the back cover, by pressing it firmly against the base of the film back, as illustrated. The back cover will automatically close and lock, with the safety lock also locking the back cover release button. The same operation will close the back cover when the film back is detached from the main body.

* 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.

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.

I. When the film back is detached from the main 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". However, it will be possible to rotate the manual film winder, and, therefore, it should be rotated 2 or 3 times more, in order to take up any slack in the loaded film.
