Bronica SQ
The Bronica SQ series is a line of 6x6 medium format SLR camera system introduced in 1980.
SQ
The Bronica SQ is a 6x6 medium format SLR camera that 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 lens system has a Seiko manufactured electronic shutter with speed of 8 sec. to 1/500 sec. plus T with the focusing helicode built-in. The sync connector is located on the front of the camera by the lens mount. Since it's a leaf shutter based camera, flash sync is available at all speeds.
An interchangeable back system was incorporated that has the ability to use a 120 or 220 (15 / 30 ) exposure film backs. The backs contain a ISO speed dial setting that is coupled to metered finders. Since the body and back need to be synchronized, make sure to wind the film crank completely before attaching the back. The film back also contains a crank. The film crank can also be removed to attach a winder or speed grip. The shutter button can be locked with a twist of the collar. The back adopted some of the dark slide features of previous models. The camera will release the back when the dark slide is inserted and pressed.
The shutter cannot be released with the dark slide inserted. Unlike the older Bronica models, when the film back is detached from the body the dark slide can still be removed. The shutter cannot be cocked without film, but use of multi-exposure mode will enable you to cock it and test fire the shutter. The lens cannot be removed or attached without cocking the shutter. A red LED will illuminate in the viewfinder during shutter fire. The light will go out when the shutter fire has completed. Observe that the cocking pin colour is green on the lens and body before attaching or removing the lens. If they are not, manually cock the shutter on the lens or body.
A battery check button is located by the shutter knob along with a cable release socket. The camera is powered by one 6v PX28 battery located in a compartment at the base of the camera. A 1/4 inch tripod socket as well as a flash sync connector for accessories are also on the base.
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 properly because there are now more electronic connector pins. The film back dark slides are now locked when not attached to the camera.
SQ-Am
A version of the SQ-A but with a built-in motorized winder. For more see Bronica SQ-AM.
SQ-Ai
The SQ-Ai has the ability to use a motor drive. Also OTF metering is possible. TTL automatic flash requires the use of the SCA connector located on the shutter side of the body for attachment to a SCA flash adapters. When multiple-exposure mode is enabled, the right of the viewfinder now displays an square indicator. A traditional bulb mode shutter setting is available instead of just T, but it drains battery power while in use. This camera switches to 4x LR44 batteries that are held by a battery holder.
SQ-B
The SQ-B is a simplified version of the SQ-A. It was made in 1996, making it the newest camera in the SQ line. The main difference with the B model is when mounted the light metering functions in prism finders are not functional. The film back also lacks the ISO dial; since a dial does not serve a purpose of coupling to the meter which will not function. The often bundled lens 80mm PS/B lens does not have a T mode. The T mode will function on lenses equipped as such. Does not have bulb mode, since the SQ-A did not have it either. The motor drive accessory also will not function with this camera.
