The Miranda Sensomat exposure meter system operates
on
the
"closed
down"
principle
of
exposure determination. An exposure
reading
is
made by closing
the
lens diaphragm down until the meter
needle, visible in the viewfinder, indicates
that
the correct
amount
of
light is entering
the
lens.
The film
must
be advanced before meter reading is made in order
to
lock
the
diaphragm in
the
closed-down position.
Failure
to
wind
the
film makes the meter activating
button
inoperative as the switch is directly connected to
the
winding
mechanism.
