Step max.
The iris control step depends on the lens. The setting value uses the value stored in the
camera. Refer to the table above for the control step number.
8.8.2.3
Position
The iris position can be set between 0 to Step Max. 0 means to open the iris and Step Max
means to close the iris. The camera initializes P-iris control and acquires iris position under the
following conditions:
1) When the camera is powered
2) When the lens is selected in P-Iris lens select
3) If the lens is changed in P-iris lens select
8.8.2.4
Current F value
The current F value is indicated by using iris position information. This can be indicated during auto
iris operation. The relation between iris position and F value depends on the lens used.
8.8.2.5
P-Iris Auto min. / P-Iris Auto max.
This function can set the control range when the iris is operated automatically. Auto max. sets the
limit when the iris goes open and Auto min. sets the limit when the iris goes closed. Auto max. can
be set to fully open but Auto min. is stopped at F5.6 as lens performance typically degrades if the
iris is closed beyond this point.

If the auto iris lens is used, this parameter should be ON. This is common for all types of
auto iris lenses.
