Bright field focusing

1
You can start viewing and focusing
before and after cocking the rapid
wind lever.
When the preview lever
is in "AUTO" (automatic)
position,
and the meter is at "OFF", the dia-
phragm is fully open except for the
moment
of exposure.
2
Turn
the distance
scale ring until
your subject image is clearly in focus.
It is not always necessary for you to
view and focus with the diaphragm
fully open.
In bright sunlight,
can
easily
focus
with
diaphragm
closed to f/5.6 or f/8 and still ob-
serve the depth of field. It is easi-
er, however,
to focus with the dia-
phragm
fully open as your subject
image is much brighter.
When the letters "MAN" appears
beside the lever, the lens is in manual
position; when "AUTO" appears, it
is in automatic
position.
Microprism
Honeywell
Pentax
cameras
have a
Fresnel
lens with a microprism
ter underneath
the ground glass.
you look through the finder, you will
see that the Fresnel lens consists of
many concentric rings which provide
the brightest
possible image on the
ground glass.
The microprism
is the center por-
tion of this diaphragm.
When your
subject is in focus, the image in the
microprism
will be sharp and per-
fectly .clear.
If
your subject is not
in focus, the microprism
will break
the image up into many small dots,
much like an engraver's
screen.
