The SBC system becomes active when the mirror starts to go up. The
mechanical switch which turns auto circuit ON is in the mirror mechanism so
that touching the shutter release alone would not drain batteries. .

Subject: Re: [OM] OM-2n 'off' shutter speed.
| I believe the OM 2 and 2n work the same regarding shooting with the meter
| switch shut off. In his book THE OLYMPUS GUIDE Milton Heilberg
indicatesthe
| following :
|
| 2. Off-
|
| a. Cds shustiem inactive
| b. Shutter-speed scale and index marks are retracted
| c. Indicator needle inactive
| d. SBC system inactive but ready to become activated at the press of
the
| shutter-release button.
| e. SBC systme will not function properly at slow shutter speeds.
Longest
| shutter speed will be determined by the ASA setting (approximately 1/30
sec
| for ASA 100.
|
| If the system demands a shutter speed less than 30th of a second the
shutter
| will still fire at 1/30th. The SBC system is inactive until the
| shutter-release is pressed regardless of which of the three positions the
| On-Off switch is in. The final shutter speed is determined by the SBC
| system.
