Center your main subject in the viewfinder and check
• the exposure information. Remember that in the manual
mode, centerweighted metering is always in operation regard·
less of the position of the metering control button . The selected
f·number is shown through the ADR window. When the shutter
release button is depressed halfway, the LCD shows the selected
shutter speed preceded by the letter M.
If the
-+
indication is displayed above the M, you will get the
correct exposure with the selected combination of aperture and
shutter speed. If only - is shown, this indicates possible under-
exposure; use a wider aperture or a slower shutter speed . If only
+
is shown , this indicates possible overexposure ; in this case,
use a smaller aperture or faster shutter speed.
M250 and B Settings
At M250 and B, the FA's shutter is mechanically con-
trolled without the exposure meter being activated or
exposure information appearing in the viewfinder.
At M250, the shutter operates at a mechanical speed
of 1/250sec . This setting is used when the batteries are
depleted and other shutter speeds are not operable. It
also can be used for flash photography.
At B, the shutter remains open for as long as the shutter
release button is depressed . B is especially useful for
making long time exposures with a cable release and
tripod .
A locking mechanism is provided between 1 and M250
on the shutter speed dial. To set either M250 or B,
depress the locking button
@
and rotate the dial to
either M250 or B.
- At these mechanical settings, you must depress the shutter
release button
a
little bit more than at other settings to trip the
shutter. Note that with the Soft Shutter Release AR-9 attached,
you cannot release the shutter at these settings.
