Pentax ZX-5N - Manual (Page 61)

When an F or FA lens is used, an approximate aper­
ture indication will appear in the viewfinder when the
shutter release button is depressed halfway. When
lenses other than an F or FA series are used, no ap­
proximate aperture indication will appear in the view­
finder.
When lenses other than an FA and F series are used,
use either the center-weighted metering or the spot
metering.
The multi-segment metering mode cannot
be used.
When the f/1.2 lens is in use with the lens aperture
ring set at a position other than the [ A ] position, the
center-weighted metering mode will be set instead of
the multi-segment metering mode. As the exposure
will come out 1 stop overexposed, set the lens aper­
ture ring to [ A ] or adjust the exposure deliberately
1 stop under.
* Exposure Warning
If the subject is too bright or too dark, the selected shut­
ter speed will blink in the viewfinder and on the LCD
panel as a warning as shown. When the subject is too
bright, choose a smaller aperture, if available; when it is
too dark, choose a larger aperture, if available. When
the shutter speed indication stops blinking, you can
take the picture. If both shutter and aperture blink, it
means that the exposure is out of metering range, un­
able to obtain a correct exposure even if the aperture is
adjusted. Select a darker subject if it is too bright, or
use a flash if it is too dark.
