ASAHI Pentax KX - Compose and Focus; Cross-microprism System; Split-image System; Shutter Operation

While viewing through the view-
finder, turn the focusing ring
until your subject comes into
sharp focus. Depending on the
type of focusing screen you have,
there are two ways of doing
this :
Cross-microprism focusing syst em
A cross-microprism focusing
system consists
of a Fresnel
lens,
made up of many
concentric rings, with a
microprism center underneath
the ground glass. With this system,
when
your subject is in focus,
the image in the microprism
center will be sharp. If your
subject is not in focus, the
microprism will break the
image up into many small
dots.
A
split-image focusing system
consists
of a Fresnel lens with a
horizontally divided screen
under the ground glass. With this
system, when your camera is held
horizontally and the image is not
in sharp focus, all vertical lines
seen through the viewfinder will
appear to be divided into upper
and lower portions. To focus,
simply adjust the focusing ring
until the upper and lower
portions are in perfect al ignment.
UTTER
Turn the shutter speed dial clockwise or counter-
clockwise to the shutter speed desired. The shutl .!,
speed may be set either before or after cocking
the rapid-wind lever. As you cock the shutter by
turning the rapid-wind lever, the "cocked"
indicator turns to red showing that the shutter is
cocked. The
indicator blacks out as you trip the
shutter button . For use of the X setting on the
shutter speed dial, refer to page 16.
With the shutter speed dial set on B (bulb), the
shutter will stay open as long as you depress the
shutter button. As you release your finger from
the shutter button, the shutter closes. When a
long exposure is desired while using the B setting,
set
the shutter button lock by moving the lever
to the left (an "L" becomes visible) while
depressing the shutter button. Alternately , use
a
cable release with a locking device for a
time exposure.
At slow speeds - sl ower than 1 / 30 - support
your camera rigidly to prevent camera movement.
To protect the shutter mechanism, trip the
shutter release before putting the camera away
for any extended period .
