• Manual Focus Mode
Manual Focus has both a Standard Mode and a
Variable Mode. Standard Mode focuses at a fixed rate
of speed. Variable Mode has eight speed levels that
can be set using a VISCA Command.
In these standard and variable modes, it is necessary to send Stop
Command to stop the zoom operation.
• One Push Trigger Mode
When a Trigger Command is sent, the lens moves to
adjust the focus for the subject. The focus lens then
holds that position until the next Trigger Command is
input.
• Infinity Mode
The lens is forcibly moved to a position suitable for an
unlimited distance.
• Near Limit Mode
Can be set in a range from 1000 (∞) to F000 (1 cm).
Default setting: D000h (30 cm)
White Balance
White Balance has the following modes.
• Auto White Balance
This mode computes the white balance value output
using color information from the entire screen. It
outputs the proper value using the color temperature
radiating from a black subject based on a range of
values from 2500K to 7500K.
This mode is the factory setting.
• ATW
Auto Tracing White balance (2000K to 10000K)
• Indoor
3200K Base Mode
• Outdoor
5800K Base Mode
• One Push WB
One Push White Balance is a function that forcibly
captures the white color once the lighting conditions
to illuminate the subject are set, enabling you to shoot
the image in the conditions as they are set. By using
this function, the natural color of the subject can be
obtained without being affected by the surrounding
lighting conditions. To set this mode, shoot the
subject that you want to capture the white color and
send the One Push White Balance Trigger.
• Manual WB
Manual control of R and B gain, 256 steps each
Automatic Exposure Mode
A variety of AE functions are available for optimal
output of subjects in lighting conditions that range
from low to high.

AF capability is low.
In high speed mode, the shutter speed can be set up to
1/10,000s. The iris and gain are set automatically,
according to the brightness of the subject.
