The Bronica SQ is a 6x6 medium format SLR camera system introduced in 1980. It replaced the Bronica EC as their 6x6 format camera.

Similar to the 6x4.5 based ETR series that came before it, the SQ uses a leaf shutter based lens design. They are not compatible with the older series of focal plane shutter cameras. The camera is powered by one 6v PX28 battery.

SQ-A

In 1982 the SQ-A was released with mirror lock up and a new view finder system now supporting Auto exposure. The newer AE finders are not fully compatible with the older SQ cameras, they are unable to mount because there is a new electronic connector pins.

SQ-Am

A motorized winder version of the SQ-A. For more see Bronica SQ-AM.

SQ-B

The SQ-B is a simplified version. The main difference is, when mounted the light metering functions in prism finders are not functional. The film back also lacks the ISO dial. The bundled lens 80m PS/B lens does not have a T mode. T mode will function on lenses equipped as such. The Motor Drive accessory will not function with this camera.
