Borrowing from Panasonic's broadcast line of video cameras, Dual Native ISO helps to achieve a balanced combination of low noise and high sensitivity to better suit working in a variety of lighting conditions. Two dedicated circuits are provided for each pixel: a Low ISO circuit provides base sensitivities of ISO 100 for normal use, ISO 640 when V-Log is applied, ISO 400 when HLG is applied, and ISO 200 when Cinelike D2/V2 is applied; a Low Noise circuit provides base sensitivities of ISO 640 for normal use, ISO 4000 when V-Log is applied; ISO 2500 when HLG is applied, and ISO 1250 when Cinelike D2/V2 is applied.
