I recently got the Speed Grip S for my Bronica SQ-Ai. However I don't have a manual for it and I hope someone using it can help me out. I have attached it to my body and the winding crank works fine. But it seems that I need two strokes to get the body ready for a shot. The first crank lowers the rear baffle and the second one brings the mirror up to position. In other words it seems two strokes equal one full revolution of the manual crank on the side of the body. Is this correct? I was hoping that it was a single stroke gizmo.
