It is of course heavier (the whole setup weighs in at 2.5kg) but balanced very well and the grip is very comfortable to use. Overall with this grip fitted and a prism attached the camera operates very similarly to a 35mm SLR in terms of film winding and so on. S and C appear to correspond to the S and C modes of the main camera, single and continuous mirror lockup shots. The mode dial offers three modes: off, S and C. The larger button on the front replicates the shutter release button on the body (which continues to function as well) while the smaller button to the rear of the camera controls the motor – depending on the current state of the camera it cocks the shutter, winds the film and resets the mirror when it is locked up. On the top of the camera there is a hot shoe (with a plastic blanking plate, a nice touch), a mode selector and two buttons. I’m not 100% sure what this is for, I’d have guessed a battery check if the light were easier to see. On the back of the base of the camera there’s a button with a red LED next to it which illuminates slightly when the button is pressed (it’s visible in low light only). Bottom plate with battery compartment visible This also provides power to the camera body when attached. When this is released it gives access to the screw holding in the battery compartment which (very conveniently) takes 6 AA batteries. There’s also a metal plate with the bottom of the hand grip attached to it held on to the base plate with a thumb screw. The motor drive attaches to the camera using the tripod socket, a replacement tripod socket is provided on the base of plate.

Hopefully this will help the next person trying to figure one out, or at least by virtue of being wrong on the internet I’ll be able to get someone who knows what they’re doing to tell me how the thing really works. Bronica Speed Grip S For The SQ-A & SQ-AI Bronica Speed Grip S For The SQ-A & SQ-AI. Since I couldn’t find any documentation at all about it on the internet and had to figure it out for myself I figured I’d put what I figured out here.
