4.7 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 parameters to suit your lens type and your
personal preferences.
4.7.1 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 is also selected in this menu.
4.7.2 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.
4.7.3 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.
To switch on the extended iris function use the
Extended iris button
(5) 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
(33) in the viewfinder lights,
and gain and exposure controls are blocked. The parameters for the extended iris
function are set in the
LENS
menu.
4.7.4 Lens indicators
The
ND/RE indicator
(29) in the viewfinder lights when a lens range extender is
selected.
The
Iris indication
(30) in the viewfinder shows the value of the iris opening (when
enabled in the
VF
menu).
The
Zoom indicator
(38) in the viewfinder shows the degree to which the lens has
been zoomed in or out if this feature is supported by the lens. It shows 50 if not
supported.
