M: Manual

In manual mode, you control both shutter speed and aperture. While
the exposure meters are on, rotate the main command dial to choose
a shutter speed, and the sub-command dial to set aperture. Shutter
speed can be set to "v" or to values between 30 s and
the shutter can be held open indefinitely for a long time-exposure
(Bulb/A or Time/%, 0 52). Aperture can be set to values
between the minimum and maximum values for the lens. Use the exposure
indicators to check exposure.

Provided that an external exposure meter is used, the exposure ratio need only be taken into
account when the lens aperture ring is used to set aperture.

The Exposure Indicator
If a shutter speed other than Bulb (A) or Time (%) is selected, the exposure indicator in
the viewfinder shows whether the photograph would be under- or over-exposed at current
settings. Depending on the option chosen for Custom Setting b2 (EV steps for exposure
cntrl, 0 234), the amount of under- or over-exposure is shown in increments of
EV (the illustrations below show the display in the viewfinder when 1/3 step is selected
1
/
2
for Custom Setting b2). If the limits of the exposure metering or live view exposure control
system are exceeded, the indicator will flash.
