Basic Functions
AE – Gain priority
The gain can be set freely by the user to 8 steps
between –3 dB and +18 dB.
The shutter speed is fixed and the iris is set
automatically, according to the brightness of the
subject.
AE – Manual
The shutter speed (20 steps), iris (18 steps) and gain (8
steps) can be set freely by the user.
AE – Bright
The bright control function adjusts both gain and iris
using an internal algorithm, according to a brightness
level freely set by the user. Exposure is controlled by
gain when dark, and by iris when bright.
As both gain and iris are fixed, this mode is used when
exposing at a fixed camera sensitivity. Only when the
AE mode is set to “Full Auto” or “Shutter Priority,”
can you switch the mode to “Bright.”
