Me too. My EC has the same issue. I have figured out the basic circuit, but I have questions. I could use clarification of the wiring in the camera. Also, the circuit I came up with has the problem that, although it times the "shutter" (an LED), it only does so if the switch is released BEFORE the end of the time period. Might be difficult with fast shutter speeds. It appears that, with my circuit, the standard monostable circuit for the 555 chip, the shutter will remain open as long as the shutter button is held down. Unless the shutter switch in the camera somehow solves this problem. Can anyone help me?
