3.3 Focus
Focus has the following modes, all of which can be set using VISCA Commands
(CAM_Focus Command).
⚫ Auto Focus Mode
The Auto Focus (AF) function automatically adjusts the focus position to strong
contrast subject in the AF Frame. The minimum focus distance is 10mm at the optical
wide end and 800 mm at the optical tele end. The default minimum focus distance is
250mm.
- Normal AF Mode
This is the normal mode so that AF operations are always active.
- Interval AF Mode
The mode used for AF movements carried out at particular intervals. The time
intervals for AF movements and for the timing of the stops can be set in one-second
increments using the Set Time Command. The initial value for both is set to five
seconds.
- Zoom Trigger Mode
When the zoom is changed, AF starts after stopping zoom within pre-set value
(initially set at 5 seconds). After the pre-set value, even target moves, focus
operation is terminated.
⚫ AF sensitivity
AF sensitivity can be set to Normal or Low with AF Sensitivity Command.
- Normal
The follow-up ability to the change of subject becomes sensitive. Please use this
mode to photograph a subject with much movement. This mode is usually most
suitable.
- Low
The stability of the focus improves. When the illumination is low, AF does not start,
even though brightness changes to some extent, and a stable image outputs.
