Base Iso Speed; Manual Iso Speed/Gain Value - Canon EOS R5C Advanced User's Manual

Base ISO Speed

Set the ISO speed for the recommended dynamic range. You can choose from one of three base ISO speed
settings: low speed, high speed or automatic selection. Low speed is recommended for normal lighting
conditions, while high speed is recommended for low lighting conditions. The high speed setting will result in a
high ISO/gain value and low noise. Selecting [Auto Selection] will automatically change the base ISO speed
depending on the ISO/gain value.
