Film Wind And Rewind; Bright Field Focusing - Honeywell Pentax Spotmatic Operating Manual

1
Before turning the rapid wind
lever, slowly turn the film rewind
knob clockwise until a slight
resistance is felt. This prevents
loosening or warping of the film.

The first portions of the film can-
not be used for picture taking as
they have already been exposed
to light. Generally, two blank ex-
posures should be made before
taking your first picture.

film is moving from cassette to

ture is ready to be taken.

After the final picture
roll (20 or 36 exposures) has been
taken, the rapid wind lever will
not turn all the way as you stroke
it. This indicates that the final
picture has been taken on your
film, and that the film must be
rewound. DON'T open the back
of the camera, or all exposed
frames will be ruined.

Unfold the film rewind crank.
S
Depress the film rewind release
button. Turn the rewind crank
to rewind the film into the film
cassette. The film rewind crank
permits rewinding at a smooth,
even rate. (Under some atmos-
pheric conditions, erratic or too
rapid rewinding will cause static
electricity marks on the film.)
You will feel the tension on the
rewind crank lessen as the leader
end of the film slips off the take-
up spool.
Stop rewinding when you feel
this happen. AVOID DIRECT
SUNLIGHT WHEN UNLOAD-
ING YOUR FILM. (The rewind
release button will return
normal position as you load your
next film and turn
wind lever.)

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.

tion of the ground glass.
