METERING METHODS
With Minolta MD or Me (meter-coupled)
lenses, metering is done with the stop-down

at the moment of
exposure.
(Do not push the
stop-down button when MD or Me lenses are
being used normally

Stop-down metering is used for lenses other
than the MD or Me types (see p. 43) or for any
lens used with non-coupled extension tubes or
