5.6Lens 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.
