first off. it is a non pentax camera (no flames please) and am going from memory here. so it is a bit scratchy. need help in trying to remember what brand it was.
it was a 35 mm slr that was shutter prioritiy from late 60's early 70's??? it had the meter sencor in the mirror it self. many engraved lines in the mirror surface to let light to the cbs sensor. it had a leaf shutter between lens and mirror. no film plane shutter as per normal, so the mirror had to form a light tight seal to prevent film fog the VF had a needle which pointed to F stops engraved on the focus screen. I think the lens iris was part of the camera body, could have been part of the shutter (memory fade) operation was as follows. shutter leaves closed, mirror moves up, shutter opens (to F stop?) for set time (up to 1/500th), shutter closes, mirror moves down, shutter opens again. There where only 3 lens available for it. flash sync was any shutter speed due to leaf shutter. on a side note, didn't the pentax 6x7 have a leaf shutter lens with pc terminal on it? James
