The shutter release is detained in the initial position by the shutter actuation arm when the sliding member is in one of the first and offset positions. The shutter release is released from the shutter actuation arm when the sliding member is in the second position. The shutter release is biased toward the released position. The timer includes: a delay counter and a linkage coupled to the delay counter for movement, from a start configuration to an end configuration. …
