4.8.3 Studio mode selection
The Studio Mode provides a better signal-to-noise ratio to get higher quality images.
Switch on the Studio Mode in situations where lighting conditions do not require the
full dynamic range of 600% (400% IT). When the Studio Mode is on, the dynamic
range is reduced to 300% (200% IT).
The Studio Mode is switched on or off in the
VIDEO
menu. It can only be switched
when gain is set to 0dB. If you change the gain to a value other than 0dB, the Studio
Mode is switched off. However, if you reset the gain to 0dB, the Studio Mode value
returns to its last set position.

camera. The gain is selected via the up/down scroll
Gain switch
(10) on the left-front
side of the camera. When this switch is pressed initially, the current value of the gain in
dB is displayed in the viewfinder.
