Nikon Coolpix P7100DxO

At base ISO (100) read noise is 2.53 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.

Nikon Coolpix P7700DxO

The Nikon Coolpix P7700 was measured at 8 ISO settings from ISO 80 to ISO 6400. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (80) read noise is 1.32 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
