M manual mode
In mode M, you choose both the aperture and the shutter
speed. At a speed of BULB, the shutter remains open while the
shutter button is pressed.
After setting the lever as the illustration shows, rotate the
control ring to set the shutter speed, and rotate the sub dial to
set the aperture value.
• Use the exposure compensation indicator to view the
exposure difference between suitable exposure and the
exposure derived from set aperture value and shutter speed.
• The shutter speed can be set to 1/2000 – 60 sec. or [BULB].

• You can change the functions assigned to the control ring
and the sub dial. g "c Custom Menu" (P. 68)

Cautions
• Exposure compensation is not available in M mode.
Choosing when the exposure ends (bulb)
You can take a picture with a bulb exposure time in which the shutter stays open as
long as you hold down the shutter button. Time the end of the exposure to suit the
subject. Use for night landscapes and fireworks. In M mode, set the shutter speed to
[BULB].
#
Cautions
• Maximum 15 minutes (default)
• The maximum exposure time of bulb shooting depends on ISO sensitivity.
• To reduce camera shake for bulb shooting, mounting the camera on a stable tripod or
using a remote cable (sold separately) is recommended.
• The following features are not available during long exposures:
Sequential shooting/self-timer shooting/AE bracket shooting/image stabilizer/
flash bracketing.
Noise in images
While 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. g "c Custom Menu" (P. 68)
