Tamron BRONICA ETRSI Owner Manual
Congratulations on your choice of the Zenza Bronica ETRSi single lens reflex camera.
The ETRSi has been developed on the basis of the technology and experience gained with
the Zenza Bronica ETRS and is between the lens leaf shutter type single lens reflex camera
which provides full flash synchronization at all shutter speeds. When used together with
the exclusive SCA386 System Adapter (optional) in combination with specified electronic
flash units, it also has full auto-flash control based on TTL direct light measurements made
at the film plane. Used in combination with the newly-developed AE-III Prism Finder E, there
is also switching from full-area average metering to spot metering, as well as AE lock.
Although the following instructions are based on the standard ETRSi combination consisting of the ETRSi main camera body with the standard Zenzanon-PE 75mm lens, Film Back Ei
120 and Waist-Level Finder E, the choice of lens, film back and finder is, of course, left completely to the discretion of the user to suit picture taking needs.

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.
* When loading the battery, be sure to leave the battery removal ribbon extending out, for convenience in removing the battery the next
time.
B. Coincide the plus (+) and minus (-) marks on the battery with similar polarity indications in the battery chamber. Then, push in the negative end of the battery first and follow with the positive end.
C. 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 battery check LED lights up in the left-rear corner (of
the screen area) 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 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. Time exposure is an additional mechanical speed, accessible by a lever (A/T) on the lens.
* The batteries noted may be obtained at any photographic equipment or electrical appliance shop.

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.
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. But, if winding is
possible, rotating the film winding crank until it stops will automatically take care of the
incomplete action, whether uncocked 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.
* 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. Using a Polaroid Land Pack Film Back will provide an instant color or black and white picture, used typically for checking the lighting and/or composition before taking the actual
photograph.
* Choose film backs to match your photographic requirements, as various types and formats
are available optionally.
5. The film chamber that can be attached or detached freely, thus permitting changes in
film types even in mid roll. The camera body and film back are fully coupled upon connection. This means that the back and body communicate their state of readiness to each other,
and prevent accidental double exposures, or blank frames.
After attaching the film back, wind the crank. If winding is not possible, all preparations for
taking the picture have been completed. But, if winding is possible, the wind will automatically take care of any incomplete action, whether uncocked shutter or film not advanced.
Thus, any back can simply be attached to the body without need for checking the body, or
back for their state of readiness.
3. Attachment and Removal of Film Back
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. 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.
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.
*Various film back types and formats are available optionally.
Therefore, choose those suitable for your needs. See instructions supplied with the Polaroid Land Pack Film Back and Film Back ETRS 135
for their proper use.

3. Attachment and Removal of Film Back (con’t)
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 cannot be withdrawn while the film back is removed
from the main body.
5. Film Loading
9
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.
* Be especially careful regarding the running direction of the film.
When properly loaded, the inside black surface of the leader must
face outward when running across the pressure plate, as illustrated.
E. Rotate the film back winding crank on the right side of the film
holder 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 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.
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.
* The spool holders on the left side will be locked securely, when
back cover is closed.

When loading 220 roll film in its exclusive film back, do not mistake
the dotted line for the starting point, as it is located before the arrow
marks.
I. The film back winding crank is used for advancing the film, when
the film back is detached from the main body for film loading.The
film back winding crank 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.
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.
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. 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 body.
