Exposure Modes - Pentax PROGRAM PLUS Manual

EXPOSURE MODES
This Pentax camera provides four different
exposure modes. Choose the mode that suits
the photographic situation and the subjects or
feelings you want to express.
When using conventional Pentax K and Kf mount
lenses on this camera, you can use the Aperture-
priority AE, Metered Manual and all conventional
Auto Flash modes. When using new "A" series
lenses, you can also select Programmed AE and
Programmed flash modes. The reason for this is
that those modes are only available when the
lens has an "A" (auto aperture setting).
