Congratulations on your choice of the Zenza Bronica SQ-Am single lens reflex camera which has been
developed to provide the user with high quality performance, simple handling convenience and extremely
useful versatility plus automatic motorized film winding and shutter winding operations suitable for the
professional photographer.
Although the Zenza Bronica SQ-Am has been designed exclusively for motorized operations, it has, also, been
developed as a complete modular "system" camera possessing complete interchangeability with the
interchangeable lenses and accessories developed for the SQ and SQ-A models, on which the SQ-Am is also
based, and, therefore, provides the user with a very high degree of motorization in daily operations, in addition
to automatic film winding and shutter winding actions. Although instructions following are based on a standard
combination consisting of the SQ-Am main body with Zenzanon-S 80mm lens, Film Back SQ 120 and Waist
Level Finder S, the choice of the lens, film back and finder is left to the discretion of the photographer, who
should choose those items best suited to the type of assignments contemplated.
To obtain best results from the Zenza Bronica SQ-Am, may we suggest that you read this instruction manual
through carefully, before you even touch the camera, as your pleasure in using the camera will be even greater
if you thoroughly familiarize yourself with its working parts before loading your first roll of film.

1. Loading the Batteries
A single 6 volt silver oxide battery or alkaline-manganese battery is required for the electronic control lens
shutter. The  electronically-controlled shutter system will not work without loading the battery. The shutter will
be mechanically controlled when the battery is not loaded and will be released at 1/500 sec., regardless of the
setting on the shutter speed dial.

Six 1.5 volt AA-size alkaline manganese or NiCd batteries are required for the motor drive system.
However, the performance noted in the specifications will not be possible when manganese batteries are used
because of their electrical characteristics.
*The batteries noted may be obtained at any photographic equipment or electrical appliance shop.





A. Set the mode selector switch to OFF. Then, slide the battery chamber button in the arrow indicated direction
which will permit the cover to be taken off.
The battery chamber cover is closed by, first, inserting the bottom end and then pushing the top end until it
locks.

B. Taking out the upper battery holder will expose a lower battery chamber which is for the 6 volt battery of the
electronic shutter. Coincide the plus (+) and minus (-) marks on the battery with similar polarity indications in
the battery chamber, when inserting the battery, and then push it in with your finger.

* The shutter will be mechanically-controlled at 1/500 sec. when the battery is loaded with polarity marks
reversed.

C. The six AA- size batteries for the motor drive system must be loaded in the battery holder taken out, with
their polarity marks coincided to the indications on the holder. The battery holder in which the batteries have
been loaded must be inserted into the battery chamber in the arrow- direction indicated on the holder.

2. Battery Checking





A. Set the mode selector switch to Sm or Cm and then depress the battery check button. If a red-colored LED
lights up at the rear end of the shutter speed scale window, the battery for the electronic shutter is loaded
properly and there is sufficient power for operations. * If the LED does not light up, (1) Mode selector switch is
on "OFF" position, (2) the battery is not loaded properly or (3) it is completely drained and should be
exchanged.
B. The batteries for the motor drive system are checked by setting the mode selector switch to Sm or Cm and
depressing the drive button to check whether there is motor drive operation or not.

3. Exchanging Lenses
The Zenza Bronica SQ-Am will not operate properly unless the lens is attached. Furthermore, it will not be
possible to attach or remove the lens unless both main body and lens are in the "wound" condition, with the
winding pin on the lens positioned between the red-colored band and green-colored dot and the winding pin of
the body set to the green dot. When the winding pins are not located properly for attaching the lens, simply
move the winding pin of the lens to the green dot manually, with your finger, and press the drive button to wind
the lens shutter when the winding pin of the main body is not located at the green-colored dot.





                            A. To attach the lens to the body, align the orange dot on the
                             camera main body and the red dot on the lens, and then insert the
                                  lens fully into its mount. Rotate in the counterclockwise direction
                                      until it stops, with an audible click, which will indicate that it is
                                 securely locked.

B. To detach the lens, press the lens release button down and, at
                                  the same time, rotate the lens in the clockwise direction until it
                           makes a full stop, at which point it will be possible to detach the
                                      lens.




4. Functions on the Hand-Grip



                        A. The mode selector switch has three settings, or OFF, Sm and Cm.
                   When set to OFF, all power is switched OFF and auto winding, lens
                              shutter operation and the built-in exposure meter of attached finders
                              will not function. When set to Sm, there is single exposure operation
                        and when set to Cm, there is continuous exposures while the shutter
                             release button is depressed.





                           B. The drive button is used to set the loaded film to the first frame to
                          be exposed, after it is aligned to the start-mark, to advance the film
                                for multiple exposures, etc.

                           C. When there is abnormal overload on the motor during film
                          winding operations, etc., the motor will stop and the red colored
                            overload warning LED will light up. Therefore, move the mode
                                selector switch to OFF, check for the cause of the overload and
                                 rectify it. Then, set the mode selector switch to Sm or Cm and it will
                          be possible to continue shooting.
                        OFF, check for the cause of the overload and rectify it. Then, set the
                      mode selector switch to Sm or Cm and it will be possible to continue
                              shooting.




D. The accessory shoe is a hot shoe type which means that electronic flash units with proper terminals can be
used without connecting cords. However, the contact cover on the hot shoe must be removed, first, when
attaching electronic flash units.

E. Depress the shutter release button gently, with the ball of the finger.
When the shutter release button is stroked gently and smoothly, it will be possible to confirm the shutter speed
setting in the viewfinder area of the AE Prism Finder S, when it is attached.

5. Shutter Release Warning LED


                                 In the following cases, the shutter will not be released and a shutter
                                  release warning LED will light up, outside the screen area, in the
                                top center of the finder:
                           1 . Dark slide is inserted.
                                    2. Lens is not attached properly. (Same with automatic extension
                                  tubes, too.) 3. Lens release button is depressed.
                                    4. Film is not advanced. (Same when exposure counter is between
                              "S" and "1 ".) 5. Batteries for motor drive operation does not have
                                    sufficient power.


6. Attachment and Removal of Film Back
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 film back is fully coupled to the camera main body, upon attachment. Therefore, the shutter will not be
released, even when the shutter release button is depressed if the film back is attached with the film still not
advanced properly, and the shutter release warning LED will light up instead. The drive button should be used,
in this case, to advance the film one frame.
On the other hand, should the drive button be depressed when a film back is attached with film advanced
properly and, therefore, in condition for photography, the film will not be advanced.
Thus, it is possible to choose the film type most suited to the shot, even midway in the roll. An ASA/ISO film
speed dial is available on the film backs and can be used for setting the film speed of the film loaded in the film
back, as there is automatic
coupling when finders with built-in exposure meters are attached on the camera body. This will, of course, be
very convenient when using films of different sensitivities in the film backs.

* 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. A Single SQ-Am can be used by many in the studio or at home, by using additional film backs.
* Film backs are available optionally. Therefore, the type meeting the requirements of the photographer should
be chosen.

A. To attach the film back to the camera main body, simply insert the latches at the upper end of the film back
into the attachment openings at the upper end of the camera main body. Then, press the lower end of the film
back against the 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. Furthermore, 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 rule to withdraw the dark slide promptly upon attaching the film back to the main body.

B. To remove the film back from the camera main body, insert the dark slide into the dark slide slit, as
illustrated, with the O mark on the dark slide at the top end. Push it all the way in.

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 from the film back when the film back is detached from the camera main
body.

7. Construction of Film Back





   A. The film back consists of a film holder and a film back frame, with exclusive film backs available for
      120 and 220 roll films.
   B. 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 has a base with a dark slide slit and a back cover with an ASA/ISO film speed dial
      and a film type indicator frame. The film back frame completely encloses the film holder and shields it

14. Setting the Shutter Speed Dial





                              A. The shutter speed scale is viewed
                                      in its window over the shutter speed
                                          dial. The numbers on the scale are
                                      shutter speed settings, with numbers

* The shutter is released at 1/500 sec., regardless of the setting when the battery is not loaded or is completely
drained.
B. The numbers on the scale are color-coded in orange and white. Orange-colored numbers are full number
settings of 1 second and longer while white colored numbers are setting from 1/2 to 1/500 second. There is no B
(bulb) setting. See the page 21 for time (T) exposures.

15. 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, therefore, must be
                           unlocked for use.
                          Except when using the lever for time exposures, always shift it so that
                              the letter "A" is visible on the lens barrel and tightly lock its set screw
                               to prevent accidental movement.

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.
                           B. Slide the time exposure lever and expose a red-colored "T" on the
                              lens barrel. Depressing the shutter release button, in this condition,
                               will open the shutter. The shutter is closed by shifting the time
                           exposure lever and exposing the letter
                        "A" once more. However, since the film will not be advanced to the
                            next frame, in this case depress the drive button to advance the film.



16. Setting the Aperture


                                                   A. The aperture ring is rotated, in

                                                  * Intermediate settings cannot be used
                                              when the finders with built-in

B. All interchangeable lenses for the Zenza Bronica SQ-Am have fully automatic lens diaphragms which means
that the focusing screen is always viewed at the full aperture, with the brightest possible image. However,
depressing the depth of field preview lever will stop the lens diaphragm down to the preselected lens opening
and permit the photographer to check the depth of field effect on the focusing screen.

* The aperture ring must not be adjusted while the depth of field preview lever is being depressed.

20. Distance Scale and Depth of Field Scale
View original page 21
Page 22 · Read text
A. Distance scales on the Zenzanon-S lenses can be used for
                             focusing at the required distance or finding the distance actually
                              focused. Simply rotate the focusing ring and set the required distance
                              opposite the orange-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. The depth
                               of field scale shows the zone of apparent sharpness at any lens
                            opening or distance and can be utilized for quickly and simply
                                ascertaining the depth of field. The depth of field scale is next to the
                               distance scales and is made up of identical pairs of apertures on both
                                sides of the orange-colored distance index. These identical pairs of
                               apertures indicate the distance that will be in focus at these lens
                              openings. For example, if the 80mm lens is focused at a distance of
                         3m, it can be seen from the depth of field scale that the zone will
                             extend from 2 to 7 meters (6 ft. to 23 ft.), when a lens opening of
                         F22 is used.
                          * See the depth of field table for the Zenzanon-S 80mm lens, on
                           page 40.



21. Infrared Photography



                          In infrared photography, some adjustment must be made in the focus in
                         order to retain sharpness on the film, because the invisible infrared rays
                          are longer in wave length than the visible rays used for focusing.  For
                           infrared photography

                            1. Use a R filter or equivalent with an infrared (black-and white) film.



2. The red-colored line, next to the orange-colored distance index, is the infrared index.
3. After focusing in the normal manner, re-set the distance indicated by the orange colored distance index to the
infrared index, by shifting the distance ring.
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.

22. Flash Photography

A. Always use flash cords with a standard PC type plug. When
                                 detaching the flash cord, grip the plug firmly and pull it out
                                        straight, instead of using a twisting action.

                               B. The lens shutter of the Zenzanon-S lens 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.
                                This means, of course, that flash fill-in for daylight shots can
                                   also be made very easily.
