The minimum ISO sensitivity is higher than usual because S-Log2 or S-Log3 uses a different kind of exposure control to achieve a wide dynamic range.

S-Log2 and S-Log3 have gamma curves that enable recording with a wide dynamic range. In order to achieve this wide dynamic range, the camera controls the exposure differently than when recording with S-Log2 or S-Log3. This makes the minimum available ISO sensitivity of the camera higher.

Noise will be visible when you record with high ISO setting. Record on a lower ISO setting to avoid noisy images. To compensate for brightness you can try one of the following:

  • Use higher Aperture setting
  • Use slower Shutter Speed
  • Adjust the brightness after recording with an editing software
