Allows you to set the aperture and shutter speed manually. You can check how much it differs
from the appropriate exposure by using the exposure level indicator. This mode gives you more
creative control, allowing you to make whatever settings you like, regardless of the correct
exposure.
Set the mode dial to M and turn the control dial to set the value.
• Shutter speed: Turn the control dial to set the value.
Aperture value: Turn the control dial while holding down the F button
to set the value.
• The range of aperture values available varies with the lens type.
• The shutter speed can be set to 1/4000 – 60 sec. or [BULB].
• The aperture value and shutter speed change in 1/3 EV increments as
the dial is turned.
• In M mode the exposure level indicator will appear on the super control panel screen. It
shows the difference (ranging from –3 EV to +3 EV) between the exposure value calculated
by the currently selected aperture and shutter speed and the exposure value considered
optimum by the camera. If the difference exceeds ±3 EV,
vw will appear in red on both sides
of the indicator.
Noise in images
During shooting at slow shutter speeds, noise may appear on-screen. These phenomena are
caused when current is generated in those sections of the image pickup device that are not
normally exposed to light, resulting in a rise in temperature in the image pickup device or image
pickup device drive circuit. This can also occur when shooting with a high ISO setting in a high-
temperature environment. To reduce this noise, the camera activates the noise reduction
function.
