IMPRINTING THE REPRODUCTION RATIO
The
OAT
A button on the side
of
the lens barrel
determines whether or not data
will
be
displayed
in
the
viewfinder and imprinted on the film.
When
the
OAT
A button
is
pushed once, it remains
in
the down or
ON
position. I n this case, the reproduction
ratio set on the
lens
appears
in
green
at
the lower right-
hand corner of the viewfinder
image
as
soon
as
the
ringlight flash
is
ready to fire. Because the data glows
when the flash
is
recycled, you can
use
it
as
a ready-light.
Then, at the instant
of
exposure, the data
is
imprinted
at
the same place on the
film
frame.
With
the 2X close-up
attachment lens
in
place, the reproduction ratio between
O.8X
and 2X
will
be
displayed and imprinted
in
green.
Press
the
OAT
A button a second time, and it returns to
the up or OFF position.
With
the button
in
this position,
data
is
not visible inside the viewfinder nor
will
it
be
imprinted on the film.
If you shoot with the focusing ring set between click-
stops, the reproduction ratio
will
not
be
shown correctly
inside the finder.
In
this case, make sure the
OAT
A
button
is
in
the OF F position,
so
that the incorrect data
will
not
be
imprinted on the film.
Note:
When using
color
film,
the
imprinted
data
may be
difficult
or
impossible
to
read if
the
background
in
the
lower right-hand
corner
of
the
frame
is
green;
with
black·and-white
film, it
may
not
show
up if
the
background
is
light in
tone
.
