Robert Lewis Posted October 7, 2011 Share Posted October 7, 2011 Is any Arri 16 S owner or user able to advise me whether the shutter stops in the closed position when the camera is stopped, or is the stopping position random - sometimes closed and sometimes open or partly open? I have looked at as much material about the camera as I have found, but there is no mention of this. Link to comment Share on other sites More sharing options...

Premium Member John Sprung Posted October 7, 2011 Premium Member Share Posted October 7, 2011 It's random. You develop the habit of inching it open when you cut. That was easier on the models I and II, where the inching knob is near your right thumb. They could have given it a hard stop, but that wouldn't be good for the high precision mirror shutter. -- J.S.

Premium Member Tim Carroll Posted October 9, 2011 Premium Member Share Posted October 9, 2011 Yeah, no one ever made a motor for the 16S that stopped the shutter in the closed position. I talked with Clive Tobin about it one time. The main issue is the rubber coupling, which can slip as it wears and stretches, so there really isn't a direct connection from the motor on the 16S to the shutter. All power goes through that rubber coupling. The reason Cinematography Electronics was able to make their crystal sync motor stop always with the shutter in the closed position with the Arriflex IIC is that even though there is a rubber bushing in the motor coupling on that camera, that star shaped bushing doesn't slip. Best, -Tim Link to comment Share on other sites More sharing options...
Robert Lewis Posted October 20, 2011 Author Share Posted October 20, 2011 Thanks all for the information. I have been away for a little time and hence not able to express my appreciation before now. Link to comment Share on other sites More sharing options...
