Whor

dicphrcgm?
One
of the
superb f eatures
of
the
Minolta
SR-
1
is
its completely
automatic
pre-set
diaphragm.
In a
conventional
single
lens
reflex
camera, when
the
lens
is stopped
down
the
visual
f ield
of
view
becomes
darker
thus
making
it
dif
f
icult
to
focus.
In
the
Minolta
SR-
1,
the lens is
completely
automatic
ancl
pre-set;aperture
is always
at
maximun
opening
unti I
the
shuttter is released.
Consequently,
focusing
can
be
quickly
determined
through the extra bright
viewfinder
no
matter what
aperture
you
have
preselected.
When the shutter
is
released,
the diaphragm
closes
to
pre-set
aperture,
the mirror
clears, the
picture
is
taken
the
mirror
returns,
the
diaphragm re-opens to
maximum
aperture...all
simultaneously,
all
automatically.
