D. Preparing the camera and shooting
ISO can be a little more confusing. ISO is used to 
determine the correct exposure for a camera when using 
an external light meter. As different gamma curves require 
slightly different exposure levels the optimum ISO (native 
sensitivity) will vary depending on the gamma curve used.
STD Gamma curves = 800 ISO = 0dB
Hypergamma HG1, HG2, HG3, HG4 = 800 ISO = 0dB
Hypergamma HG7, HG8 = 1600 ISO = 0dB
S-Log2 and S-Log3 = 2000 ISO = 0dB
If you double the ISO, for...

D3.2 To select the use of gain or ISO 
(MENU: Camera – ISO/Gain/EI – Mode). 
Manual gain control is then done via the gain switch on 
the side of the camera body the gain or ISO level assigned 
to each of the 3 switch positions can be set in: 
(MENU: Camera – ISO/Gain/EI – ISO/Gain) etc.
To enable/disable automatic gain control press the  
Gain button on the camera body.
If using the Cine EI mode please see the section on 
“Exposure Index”.

D4. White Balance (Custom Mode) 
Setting the white balance correctly ensures that white 
objects in the scene appear white and that the overall 
color response of the camera is true to life. There are 
several ways of setting the white balance.
Pressing the white balance button on the camera will 
toggle between automatic white balance (ATW) and  
the white balance function selected by the white  
balance switch.
ATW: The camera can determine the correct white...

D4 .1  Preset
The white balance can be fixed to a set value. When the 
white balance switch is set to PRESET the preset value 
is used. To change the preset value go (MENU: Paint – 
Preset White) and select the desired color temperature.
D4.2 Memory Mode A and B
There are two memories in the camera that will remember 
the white value for a white target. To set the white balance 
correctly aim the camera at a white target such as a piece 
of white paper that is...

D6. Exposure, Zebras, Waveform and Histogram
Exposure is controlled through a combination of shutter 
speed, gain/ISO, iris aperture and ND filter. The camera 
includes a number of tools for measuring exposure.
D6 .1  Zebras
Zebras are commonly used to measure the brightness of 
either skin tones or highlights. Zebra 1 is designed to be 
used for skin tones. (MENU: VF – Zebra). For STD gammas 
the default level of 70% works well in most cases, a small 
amount of...

D. Preparing the camera and shooting
In (MENU: VF – Zebra - Select) you can choose whether to 
show zebra 1, zebra 2 or both in the viewfinder. The zebras 
can be turned on and off via the push button on the side 
of the viewfinder or with (MENU: VF – Zebra – Setting).
In Cine EI when a MLUT is enabled for the Viewfinder the  zebras measure the exposure levels of the MLUT as seen on the viewfinders LCD screen, not the S-Log2 or S-Log3 recording level.

D6.2 Waveform Vectorscope and Histogram
These are selected via  (MENU: VF  – Video Signal Monitor).
Waveform: The waveform display measures the 
brightness of the recorded image and displays the 
brightness levels on a vertical scale that goes from 0% 
or black at the lower dotted line at the bottom to 109% 
(clipping point) at the top. There are additional dotted 
reference lines at 25, 50 75 and 100%. The left side of the 
waveform meter represents the left side...

Vector: This is a vectorscope which is used to measure the 
color levels and color hue of what is being shot. In most 
cases it is not necessary to use the vectorscope.
Histogram: The histogram displays the exposure 
brightness on a horizontal scale where black is at the 
left and 109% (clipping point) is on the right. The vertical 
height of the indicated level represents the amount of the 
image that is exposed at that brightness.

Video Signal Monitor Source: When shooting in the   
Cine EI mode it is possible to select whether the video 
signal monitor displays the levels of the recorded signal 
or the level of any LUT being used. Please refer to the 
Cine EI section of this guide to better understand which to 
use. The selected source signal is indicated just above the 
signal monitor.

D 7.1  In Custom Mode the iris of an electronically controlled 
lens can be controlled automatically or manually. In the 
Cine EI mode only manual operation is possible.
In Custom mode pressing assignable button 2 (iris) 
toggles between manual and automatic control. When 
manual control is selected the Iris Push Auto button can 
be used to momentarily set the iris automatically. When 
using auto iris it is possible to include an offset to the...
