The camera is equipped with two [NATIVE ISO], [800ISO] and [5000ISO], which are called as dual native ISO.
By installing the sensitivity switching circuit inside the image sensor, a high sensitivity and low noise [5000ISO] is realized.
However, the sensitivity will drop 1Stop when [MAIN PIXEL] is set to [2048×1080 CROP]/[1920×1080 CROP] and [MAIN CODEC] is set to [AVC-Intra2K-LT]/[AVC-Intra-LT]. [NATIVE ISO] will become [400ISO] and [2500ISO].
The latitude will decrease according to the value when ISO range lower than [NATIVE ISO] is used.
[dB]
There are two gain modes of [NORMAL] and [HIGH]. The standard sensitivity equivalent to [NATIVE ISO] is set as 0 dB.
However, when the gamma curve is set to [VIDEO45]/[VIDEO50]/[BC GAMMA], the dynamic range will be set to 600%, which is less than [V-Log] or other gamma curve. Therefore, the standard sensitivity will decrease.
