4. The f-stop that you have selected and appro-

priate aperture indication determined by the

camera can be seen in the viewfinder when

the shutter release button is depressed

halfway.

• The approximate aperture indication appears in

the viewfinder. It may not the same indication as

you select the lens aperture ring especially when

the A645 150mm f/3.5 or A 645 45-85mm Zoom

f/4.5 is attached.

* Exposure Warning

If the subject is too bright or too dark, the selected

shutter speed will blink in the viewfinder and on the

LCD panel as a warning as shown. When the sub-

ject is too bright, choose a smaller aperture, if avail-

able; 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 expo-

sure is out of metering range, unable 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.
