Chapter 5 - Operating instructions
5.6 Lens preferences
When you fit a lens to the camera you may need to adjust the back focus. Refer to the lens
manufacturer's instructions to find out how to do this. The LENS menu allows you to choose
and, if necessary, adjust other parameters to suit your lens type and your personal
preferences.
5.6.1 Lens type
In the LENS menu select the lens type from two predefined settings: standard (Std) or wide
angle (WA). This gives you the optimum shading settings for either a standard or wide angle
lens. The lens manufacturer and the lens interface (analog or digital) are also selected in this
menu.
5.6.2 Auto iris
If required switch on the auto iris function in the LENS menu. You can also select the
parameters associated with the auto and the momentary iris in this menu.
5.6.3 Extended iris
The extended iris function automatically regulates the video signal level by adjusting the iris
opening, the gain level and the exposure time to suit the ambient lighting conditions.

Note
Assign the SW2 button to extended iris before using extended iris.
To switch on the extended iris function use the assignable button SW2 at the left-front side of
the camera. When this button is pressed once, the current value of the automatic extended iris
function is displayed. Press the button twice in quick succession to switch between on and off.
When extended iris is on, the Non-standard indicator in the viewfinder lights, and gain and
exposure controls are blocked. The parameters for the extended iris function are set in the
LENS menu.
