STOP-DOWN BUTTON
The stop-down button on your SR-T has
two settings, one for full-aperture metering and
the other for stop-down metering (see right) or
depth-of-field preview (see p. 32).
Pushing the button once after film has been
advanced wi II set it at one of these positions;
pushing it again will set it at the other. If film
has not been advanced, the button will not
operate, and the camera and lens will remain set
for full-aperture metering. They will also auto-
matically reset themselves for full-aperture
metering when the shutter is released even if
they have been on stop-down mode.

METERING METHODS
With Minolta MC (meter-coupled) lenses,
metering is done with the stop-down button at
its full-aperture position for greatest sensitivity
and accuracy. The viewfinder thus remains at
maximum brightness for utmost ease of com-
posing and focusing, with the automatic dia-
phragm closing down only at the moment of
exposure to the lens opening preset on the
aperture ring. (With an MC lens mounted on the
camera, the meter is automatically switched off
at the button's stop-down position.)
Stop-down metering is used for lenses other
than the MC type (see p. 43).
