1. Turn the shutter dial to the desired speed.
2. Look into the viewfinder and focus the subject.
3. 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. The aperture needle will disappear
from view with the stop-down slide extended.
4. Turn the aperture ring (or shutter dial) until the meter needle is aligned with
the stopped-down metering/battery check index. Choose a slower speed if the
meter needle rests below the index, or a.faster speed if the meter needle rests
above the index.
Notes:
•
You can also set the aperture first and then turn the shutter dial until the
meter needle aligns with the index. However, since intermediate settings on
the shutter dial cannot be used, minor exposure adjustments must be made
wih the lens’ aperture ring.
• The height of the stopped-down metering index is equivalent to one-half
f/stop.
