Focus-priority mode and focus assist mode
Differences in the DS-L3 operation process between using the focus-priority mode and focus assist mode are as
follows:
•
When [F.AE] (focus priority) is selected with [EXP MODE] button
If brightness of a subject changes as objectives are switched or diaphragm is adjusted, the camera gain is
automatically adjusted to minimize user’s task of focusing. Camera gain: 4600 max; exposure time: 150 ms max.
•
When the focus assist mode is selected with [F MODE] button
As [F MODE] button is pressed, F.AE automatically adjusts the exposure, then the exposure mode changes to
[MANU] automatically. Using the [F MODE] is suitable for application where switching of objectives or illumination
is less frequent. Camera gain: 4600 max.
Exposure time for the F.AE (focus priority) mode
The maximum exposure time for the F.AE mode depends on the DS camera head used and the setting for [IMG
MODE]. See the table below for details.
