Pentax w Operating Manual page 65

• Set the aperture to the s position while
holding down the auto-lock button when
using a lens with an aperture ring.
• The aperture is displayed on the LCD panel
whenever the camera is on.
• You can set a custom function to
compensate the sensitivity automatically to
obtain the proper exposure, when the
conditions set are not providing proper
exposure. See page 115 for setting Custom Functions.
Exposure Warning
If the subject is too bright or too dark, the
shutter speed will blink in the viewfinder and
on the LCD panel. When too bright, set the
aperture smaller (larger number), and when
too dark, open the aperture further (smaller
number). Once blinking stops, you can take
the picture.
If both the shutter speed and aperture value
are blinking, this indicates being out of
metering range, unable to obtain the proper
exposure even if the aperture is adjusted.
Use an ND (Neutral Density) filter if the subject is too bright.
Use a flash or faster sensitivity if it is too dark.
