Interchangeable Filmback Magazine

The standard Bronica S2A film back magazine is specially designed to accept either the 12 exposure 120 or the 24 exposure 220 roll film. With the Model-E film back magazine, you can get 16 (6x4.5) exposures on the 120 film and 32 (6x4.5) exposures on the 220 film.

Removing the Filmback Magazine

Insert the dark slide into the back. Hold the camera in the left hand. With the right hand, hold the back with thumb on the protruding edge of the dark slide. Press the dark slide inward with the thumb. This will release the back from the camera. Remove the back by tilting and lifting it off the open hinge at the bottom.

Note: The dark slide is only necessary for removing the back from the camera and should be withdrawn after the back is attached to the camera.

Film Loading

Avoid direct light on film while loading

Film Loading:

1. Lift film indicator frame and press hood lock to right. Back will spring open.
   

2. Press two knobs together and lift film holder out
   

3. Insert empty take-up spool in top and fresh film spool on bottom. Spools are inserted by pressing out against spring pressure plates on left side.
   

4. Draw leader paper down and across film pressure plate making sure that the leader paper is black side out.
   

   [page 8]

   
   

5. Insert paper end in take-up spool and wind one turn
   

6. Press two knobs together and insert film holder into film back making sure that the film holder studs snap firmly into place. If film holder is not yet in position, turn film winder slightly and push film holder again until it snaps into place. (Be sure to turn manual film winder in direction of arrow).
   

7. Advance film with manual film winder on film back until film start mark matches red dot on holder.
   

8. Close back making sure hood lock covers the red mark.
   

   [page 9]
   
   

9. The film indicator frame is designed to accept the end flap of the empty film box to indicate the type of film loaded in the film back.
   

10. Only even numbers will show in the exposure counter window after the number ''8'' appears. Odd numbers are indicated by a line. (On the Model E [16 exposure 6x4.5 back], only even numbers appear after the number ''4''. Odd numbers are indicated by a dot.
    

Removing Exposed Film

1. After taking last (12 th or 24 th) exposure, wind forward until indicator in film counter window does not move. (On the Model-E [16/32 exposure back] after the last (16 th) exposure on the 120 film is shot set pointer to ''F'' by pushing the free lever to right. Film winder will become free and the film can be quickly wound up on take-up spool).
   (see photo of film advance knob being wound)
   

2. Open back cover and take out film holder gently by pressing two knobs together.

Taking Photography

1. To cock shutter and advance film, turn crank clockwise until it stops.
   

   When winding the shutter, please be sure to keep turning the crank until it stops, even if you hear a sound half way. The sound means the shutter is wound, but the film is not advanced yet. Pressing the shutter button at this time will result in a double exposure.
   

2. Turn to desired aperture (f-stop); align to white dot. Intermediate apertures may be used between the ''click'' stops.
   

3. To open focusing hood, slide hood lock to right. To close, press down sides, then back, then the cover.
   

4. Magnifier rises when cover is pressed backwards. Press magnifier down into place before closing hood.
   

   [page 11]
   

   
   

5. Focus by rotating focusing ring while observing image on ground glass.
   

6. Distance scale provided on helicoid focusing ring shows the distance between the film plane and the object to be photographed with auto Nikkor 75mm F2.8. Footage is shown in red and meterage in white. See focusing distance table for 40mm, 50mm, 100mm, 150mm and 200mm lenses at page 22 or refer to the distance comparison table accompanying each lens.
   

7. All Bronica interchangeable lenses have automatic diaphragm, and critical focusing and viewing can be done with full aperture. Check the depth-of-field or adjust the background vignetting by depressng the preview button

8. When the preview button is depressed, the diaphragm is closed down to the preselected aperture. The depth-of-field can be visualy checked. (Critical focusing and viewing are done with full aperture).
   

Shutter

Shutter dial photo

The vertical focal plane shutter has rubber-coated curtains. Speeds are set on a single non-rotating selector. Through a special stabilizing device, there is uniformly balanced exposure across the large film area even at high shutter speeds.

High quality miniature ball bearings are used. The shutter curtain travels across the 55mm film gate in 15-16 milliseconds. The X setting for electronic flash (strobe) represents 1/40 second. Intermediate shutter speeds can be selected between the following speeds: 1-1/4 1/8 -1/30 1/60-1/1000

[page 13]

1 - Shutter Speed Selector

''X'' represents 1/40 second and is the fastest shutter speed with which electronic flash can be used. Any faster settings will result in partial non-exposure. (see ''Flash'', page 16).

2 - Selecting the Shutter Speed

The selector may be set for intermediate shutter speeds as indicated on page 13. Settings may be selected either before or after the shutter is wound.

3 - Color Codes of Shutter Speed Selector

When the dark slide is in the camera, the shutter will not work even if the shutter button is pressed. In this case, withdraw the dark slide. If the shutter does not now work, wind up the shutter once more and an exposure can be made without any loss of film.

[page 14]

Cable Release

To avoid camera movement, it is desirable to use a cable release when a slow shutter speed is used. Cable release sockets are provided both on the body release button and below the depth-of-field preview button.

[page 15]

Time Exposure Device

To close the shutter, turn the tip of the button clockwise.

Safety Lock

To set the safety lock, rotate the tip of the release button clockwise. When the red dot is in outside position, shutter is locked.

FLASH

[page 16]

Exposure Setting Device

The upper right picture shows lever position when using the 120 film. Keep pressing switch lever lock button and move lever until indicator arrow points to ''12'' mark. After the 12th exposure the film/shutter crank will wind remaining film continuously onto take-up spool with no resistance. The lower right pciture shows lever position when using the 220 film.

Switch lever lock button should be also pressed to move lever until arrow points to ''24'' mark. In this way the film/shutter crank will stop at every number in exposure counter until 24 before becoming ''free'', allowing the remaining film to be wound up on roll.

(When Model-E is used on your Bronica S2A, set the film setting device on ''S''. The film/shutter crank will stop at every number in the exposure counter until ''32''. When the pointer is set on ''F'' the film/shutter crank becomes free, allowing the remaining film to be wound continuously onto the take-up spool.)

S2A: Switch lever may be moved to the 24 exposure position at any time if you have forgotten to do so before loading.

E: If at any time during a roll the pointer has accidentally been set on ''F'', push the free wind release button up and the pointer will return to ''S''.

[page 17]

Using neck strap

The neck strap has coupling connectors at each end. Place these coupling connectors over the camera strap studs on each side of the camera, and press in, then adjust strap length.

To remove, lift or raise the metal wings on camera strap stud and simultaneously lift off the coupling connector.

[Making Double or Multiple Exposures]

Bronica S2A has a built-in protection against inadvertent double exposures. However there are times when deliberate double exposures may be desired.

A. After making one exposure, insert the dark slide and remove the back.

B. Turn the film/shutter crank until the shutter is wound. Replace the back on the camera body and withdraw the dark slide.

You can now make the second exposure.
