set to provide the proper exposure according to the shutter speed. If
the proper exposure value cannot be achieved, the closest value is set
and the aperture value is displayed in red.
• The shutter speed set in b mode is shared with a mode. Changing
the value in one mode automatically changes the value in the other
mode.
• When the shutter speed is set to a speed slower than 1/4 seconds, a
process to reduce image roughness and unevenness (noise
reduction) is performed.
• The shutter speed is always saved. Performing a reset returns the
value to the default setting. The default setting is 1/125 seconds.
