Note: The limits icon in the rangender main screen will turn green if a rangender limit other
than limit max = inf and limit min = 0 is set, otherwise the icon illuminates white.
6.2.3.7.3. Sensitivity
The invisible laser used in cnder III makes 300 measurements every second. To make
this rapid distance information more suitable for both viewing and motorised lens control,
cnder III calculates an average distance that is then displayed on the screen and used to
control the focus motor when autofocus is active.
Sensitivity allows you to increase or decrease the rate at which the ‚average‘ value is
calculated. By increasing sensitivity, cnder III will display an increased number of distance
values per second and adjust the motor position accordingly (= faster / snap reaction).
By decreasing sensitivity, cnder III will display fewer distance values per second and
adjust the motor position accordingly (= slower / smoother reaction).
Note: To track a fast moving target, increase sensitivity for a faster motor response. To track
a slow moving or xed target, reduce sensitivity for a smoother motor response.
Note: Sensitivity is available with cmotion cnder III or with other rangenders via ARRI
LCUB-1 only.
6.2.3.7.4. Autofocus
Autofocus will seamlessly match distance measurement data from the rangender with
lens data from the cPRO / cPRO PLUS or cPRO ONE hand unit to control the focus scale
of the lens automatically.
If autofocus “on“ is selected within the autofocus menu, focus will continue to adjust
automatically until turned o again.
Autofocus can be activated through a cPRO / cPRO PLUS or cPRO ONE hand unit user
function as well. This supports various autofocus trigger options including autofocus
press, autofocus toggle, and autofocus pinpoint. (For further information, please refer to
section “6.2.3.8. BUTTONS” on page 94 in this manual)
Note: In order to use autofocus with a cPRO / cPRO PLUS or cPRO ONE hand unit, a lens
le needs to be loaded, a lens motor needs to be connected, engaged with the lens and
assigned to focus. (For further information on how to create lens data, please refer to section
“6.2.3.3. LENS” on page 55 in this manual or to the cworld user guide.)
