EXPOSURE-MEMORY LOCK
Memory lock not used Used
The exposure-memory lock enables you to take
an exposure reading in the Programmed AE mode,
lock-in that reading, move your position, and then
take the picture with the prpgrammed reading.
This is particularly useful in high-contrast
conditions, such as when your subject is back-lit or
has a dark background.
1. If you are taking a portrait, you can move in
close to your subject and take a close-up reading
of the face. To hold that reading, depress
the memory-lock button; this will hold
the reading for about ten seconds, simultaneously
making the shutter speed (LED) you are using
flicker in the viewfinder at a faster speed.
2. As long as you keep depressing the shutter
• 32
button half-way while the memory lock is in use,
the memory lock will be maintained or. In other
words, the exposure will remain the same.
• When you wish to interrupt the memory lock,
just turn the main switch off.
3. R e compose your picture and shoot; the subject
will correctly be exposed. The memory lock will
automatically be cancelled as soon as you release
the shutter.
Cautions
• When the Pentax dedicated auto flash is used on
this camera, the memory lock does not work.
• If you accidentally depress the memory-lock
button with the camera in the Metered Manual
mode, the shutter speed set will meaninglessly
lock and flicker in the viewfinder.
