36 Controlling Lens and Camera
It is calculated based on focal length (zoom setting), focus
distance (focus setting), aperture (iris setting), and the circle of
confusion size.
While focal length, focus distance and aperture depend on the
physical settings of the lens, the circle of confusion can be set as
a numerical value in the hand unit.
To set the circle of confusion, do as follows:
1. Go to
LDD
>
Lens
>
Circle of Confusion
.
2. Select a circle of confusion diameter.
ADVICE
The perceived sharpness of an image depends on the lens
characteristics, the camera sensor and image processing,
the scene content, the setting of the lens and eventually the
display the image is viewed on.
The depth-of-field bar on a hand unit is just an indication for
the distance range in which objects appear in acceptably sharp
focus.
Always test the actual depth-of-field of your setup before
shooting and adjust the circle of confusion if needed.
As a guideline, we recommend the following circle of confusion
settings:
0.013mm For maximum detail contrast on Super 35 cam-
eras.
0.025mm Standard setting for Super 35 cameras.
0.035mm Standard setting for Large Format cameras.
0.050mm Standard setting for 65mm cameras.
8.4 Camera Control
The Hi-5 hand unit provides remote camera setup capabilities for
ARRI and third-party cameras. ARRI camera control is included
by default, third-party camera control requires additional licenses.
