Mode M (Manual)
In manual exposure mode, you control both shutter speed and aperture. Shutter speed can
be set to values between 30s and ¼
,000
s, or the shutter can be held open for indefinitely for
longer exposures ( ). Aperture can be set to values between the minimum and max-
imum values for the lens.
To take photographs in manual exposure mode:
Electronic Analog Exposure Display
If a CPU lens is attached and a shutter speed other than is selected, the electronic analog
exposure displays in the viewfinder and shooting information display show whether the photograph
would be under- or over-exposed at current settings. If the limits of the exposure metering system are
exceeded, the displays will flash.
When On is selected for Custom Setting 10 (ISO auto; 76), ISO sensitivity is automatically adjusted
to compensate for changes in aperture and shutter speed, with the result that changes to shutter
speed and aperture will not affect the electronic analog exposure display.
1 Rotate the mode dial to M.
2 Rotate the command dial to choose a shutter speed (see the illustration at left, below).
To set aperture (below right), rotate the command dial while pressing the
( ) but-
ton (to display shutter speed and aperture in the monitor, press the button). Check
exposure in the electronic analog exposure displays (see note below).
3 Frame a photograph, focus, and shoot.
