Zenza Bronica S2 SLR Camera
The Bronica S2 camera is a high-quality, Japanese-made camera. Even though it has the nickname the poor mans Hasselblad it is in many ways more superior in its build, quality and sharpness. The Bronica S2 was first introduced in 1972. The Bronica S2 6×6 camera taking 120 and 220 medium format film. The Bronica S2 camera is functional, and easy to use though much heavier then it’s counterpart cameras, therefore I think my Bronica S2 pictured here in this blog, works much better as a studio camera on a tripod then it’s counterpart cameras, or even my Hasselblad V series 500CM.
The Zenza Bronica S2 lens is unique, and features a wide-angle lens, and the Bronica also has interchangeable view finders. The mount and mirror design are unique. It has an extra-long telescopic lens, too, which results in sharp pictures.
With the Bronica S2 camera, loading film is easy. For many years, the Bronica S2 camera was used by professionals for wedding photographs and portraits. In fact, Bronica S2 cameras are still widely used by professional photographers. It is more affordable than other cameras, another great feature of the Bronica S2 camera is its mechanical shutter and two-part mirror. The lower part swings downward, and the upper part swings upward, this not only permits the use of deep-set lenses, but also means that the “mirror shock” of the two mirrors is in opposite directions, so a mirror lock-up is not needed. Zenza Bronica S2 accessories are easy to find. Used Bronica S2 cameras are still in high demand. Instructional manuals and repair manuals are readily available, if needed.

How to User the Zenza Bronica S2
- To cock shutter and advance film, turn crank clockwise until it stops (Be sure to keep turning the crank until it stops, even if you hear a sound halfway. The sound means the shutter is wound, but the film is not advanced yet. Pressing the shutter button will result in a double exposure).
- Turn to desired aperture (“f-stop”): align to white dot. Intermediate apertures may be used between the”click” stops.
- To open focusing hood, slide hood lock to the right. To close, press down sides, then back and then the cover.
- Magnifier rises when cover is pressed towards back. Press magnifier down into place before closing hood.
- Focus by rotating helicoid while observing image on ground glass.
- Focusing scales for standard 75mm lens and 200mm telephoto lens are shown in white and scales for 135mm telephoto and 50mm wide-angle are in red. The four red dots to the right of infinity mark (∞) show the infinity points when using infra-red film.
- Depth-of-field scale for all lenses are also shown. Line between f8 and f4 represents f5.6.
- When the preview button is depressed, the diaphragm is closed down to the preselected aperture. The depth-of-field can be visually checked. (Critical focusing and viewing are done with full aperture.)
Having selected the shutter speed and diaphragm aperture, advance the film by turning the film winding knob clockwise to a firm stop. Focus the lens and you are now ready to make an exposure. 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.
When “T”(Time) exposure is desired, set the shutter speed dial at “B”, depress the body release button and turn the tip of the button counter-clockwise to lock it in place. This will hold the shutter open. To close the shutter, turn the tip of the button clockwise.
The body release button has a safety lock. When the camera is carried with the shutter cocked, it is best to set the 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.
Making Double or Multiple Exposures:
Your Bronica has a buildt-in protection against inadvertent double exposures. However there are times where deliberate double exposures may be desired. Firstly after making one exposure, insert dark slide and remove the film-minder/Magazine. Secondly turn the winding crank until the shutter is wound. Replace the film-minder on the camera body and withdraw the dark slide. You can now make a second exposure.
Exposure Setting Device:
The 120 roll film allows 6×6 (2.1/4″ x 2.1/4″) exposures. Twenty-four exposures can be obtained on 220 roll film. Picture (A) shows lever position when using 220 roll film. Keep pressing switch lever lock button and move lever until indicator arrow points to “12″ mark. After the 12th exposure the film advance crank will wind remaining film continuously onto take-up spool with no resistance. Picture (B) shows lever position when using 220 roll film. Switch lever lock button should be also pressed to move lever until arrow points to “24″ mark. In this way the film winder crank will stop at every number exposure until 24 before becoming “free”, allowing the remaining film to be wound up on roll.

To Mount Lens: (C) Line up red dots on lens and mount. Insert gently to full stop. Twist to right (clockwise) until bayonet lock snaps closed. The interchangeable lens system of the Zenza Bronica Model S2 can be used with earlier model bayonet type Bronica cameras, The screw thread (diameter 57mm, pitch 1mm) shown in picture (C) is new with Model S2 and permits extension tube set and certain very long telephoto lenses to be mounted.
