Shooting a scene today, metered for 1/250 and f4 via the camera's LEDs. Pressed the shutter button and it "hung" open for approximately 2 seconds. This is odd because the FM2 is all manual - when you set the shutter speed, that's the shutter speed it fires at. Some autoexposure cameras will adjust your shutter speed but the FM2 isn't one. The next shot, same shutter speed, went off without a hitch, as did all 30+ shot over two rolls, previous to this error.
Anyone ever experience this with their FM2?
