18 APERTURE-PRIORITY AE 18.1 Stopped-down AE
•
If your eye will not be to the eyepiece the moment you release the shutter,
close the eyepiece shutter by pushing the lever clockwise. This will prevent
stray light from entering and adversely affecting the exposure.
18.1 Stopped-down AE
1. Following the procedure on p. 40, set the shutter dial to ”A.”
2. Look into the viewfinder and focus the subject.
3. Turn the lens’ aperture ring to the desired aperture.
4. Unlock the stop-down slide. To do this, push it in and then release it; the
slide will unlock and its red line can be seen.
5. The shutter speed is automatically selected according to the aperture set on
the aperture ring.
If the meter needle is in either exposure warning zone, turn the aperture ring
until the needle moves out of the zone.
Overexposure, underexpd ture and camera shake warnings are the same as for aper-
ture priority AE.
