With the mirror lens, since you have only 1 f stop,
just put the camera on automatic or on manual (wherein
you have to adjust the shutter speeds to center the
meter or indicator).
Olympus lens do not transmit true aperture information
to the camera body. All it does is transmit how many
stops from full open the lens is. Thus if you stop an
f2 lens down to f4, the camera knows to slow the
shutter speed the equivalent of 2 stops.
