Notes
• Whatever the operating mode of the electronic shutter,
the sensitivity of the CCD decreases with increasing
shutter speed.
• When the automatic iris is used, the iris opens wider as
the shutter speed increases, thus reducing the depth of
field.
• Under artificial light, particularly fluorescent or mercury
lamps, the light intensity may appear to be constant, but
the red, green, and blue intensities are actually changing
in synchronization with the frequency of the power
supply causing flicker. Using an electronic shutter under
such lighting could make the flicker even worse. Color
flicker is particularly likely to happen when the power
supply frequency is 60 Hz. However, if the power
frequency is 50 Hz, setting the shutter speed to
reduce this flicker.
• When a bright object is shot in EVS or ECS mode in
such a manner that it fills the screen, the upper edge of
the picture may have poor quality because of an inherent
characteristic of CCDs. Before using EVS or ECS mode,
check the shooting conditions.
You can turn on or off the EVS mode on the SW STATUS
page of the PAINT menu.
