Bronica SQ-Am

Medium format Medium Format SLR Discontinued leaf shutter · medium format 6x6 · motorized winder · flash sync at all speeds · electronic dependence · studio and weddings

Flash sync at 1/500 across the whole dial is what sets this body apart. Drag the wedding reception into a fill-flash exposure at midday, balance a strobe against a bright window in the studio, and the Bronica SQ-Am holds the highlights while the focal-plane crowd is stuck syncing at 1/60 and burning their backgrounds out. That is the leaf shutter living inside every SQ lens, and it is the whole reason this system existed.

The "Am" part is the motor. Most SQ bodies advance by hand crank; the SQ-Am has an integral winder, so the camera fires and reloads the next 6x6 frame on its own. Six AA cells drive the motor, while a separate small 6V battery powers the electronic shutter, which is the practical difference between this body and a plain SQ-A. Shoot a portrait sitting where you do not want to drop the camera from your eye between frames, or work a crowd at an event, and you are not reaching for a crank after every shot. It is heavier and chunkier than the SQ-A, and you notice it.

You shoot it waist-level off the ground glass, or eye-level with the prism finder snapped on top. The square format means no turning the camera, which is half the appeal for studio and album work. Focusing is ground glass with a screen of your choice, bright enough indoors but the usual medium-format slog in dim corners. Film loads through interchangeable 120 or 220 backs, so you can swap from color to black and white mid-shoot, or pull a back half-exposed and come back to it. The shutter speeds run from a long 8 seconds down to about 1/500, all electronically timed and all flash-synced.

Here is the honest weakness. Nearly the whole thing is electronic. Lose power and you are left with a single mechanical 1/500, the speed the shutter defaults to with no battery loaded, so every other setting depends on the cells. There is no metering or aperture-priority to limp home on, and the SQ electronics from the late 1980s are getting old. A flaky battery contact or a tired body means a crippled camera, and a proper CLA is not cheap because the leaf shutters live in the lenses while the body, finder, and backs all carry their own contacts to fault. Buy one tested, with a known-good back, and carry spare cells.

These bodies also shipped without a meter unless you add the metered prism, and even those are aging center-weighted metering prisms you should not trust for slide film or a backlit scene. Take an incident or spot reading from the Zone Light Meter app instead, place your shadows where you want them, and that reading pairs straight into the leaf shutter for daylight fill at any speed you like. Today the SQ-Am sits in the affordable end of square medium format, cross-shopped against the Hasselblad 500 series and the Mamiya RB67. People who pick the Bronica are buying that flash sync and the motor for a fraction of the Hasselblad price, and accepting that when the cells go, only that single mechanical 1/500 is waiting underneath.

How the app handles this body

  • Metering: Take an incident or spot reading in the app and place your shadows on a chosen zone, then dial that exposure in. On a body with no meter, or one whose cell has drifted with age, the app is the meter you trust.
  • Leaf shutter: The shutter sits in the lens, so it syncs flash at every speed instead of topping out at a body X-sync. Daylight fill stays open at any aperture, and the app's shutter ladder covers the leaf range.
