Miranda Sensomat - Quick Return Mirror

- QUICK RETURN MIRROR --------- __ .,...- ____________ _
!
To avoid blackouts in the rroder, it is of
great importance that the mirror returns in-
stantly
to its viewing position after a picture
has been taken. The Miranda Sensomat
is
equipped with such a mirror, which at the same
time houses
the CdS-sensing device of the
exposure meter.
At any time, before or after
the exposure, the mirror
is in its viewing
position.
!
• The coupled action between the automatic
diaphragm and the mirror
too is very
smooth, so
that when the shutter button is
pressed:
(l)The diaphragm closes down to the preset
aperture,
(2)Almost simultaneously
the mirror swings
up,
(3) Followed
by opening of the shutter
curtains and
fIlm exposure,
(4)Then , the'shutter closes, mirror returns
to normal position and the lens dia-
phragm re-opens fully.
All the above actions are instantaneous,
