Nikon Coolpix P340 vs Nikon Coolpix P6000: read noise comparison

Dual gain: Nikon Coolpix P340 ISO 12800, Nikon Coolpix P6000 none.

Nikon Coolpix P340DxO

The Nikon Coolpix P340 was measured at 9 ISO settings from ISO 80 to ISO 12800. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (80) read noise is 1.13 DN. A second gain (dual gain) kicks in at ISO 12800, cutting input-referred read noise by about 1.5 stop. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.

Nikon Coolpix P6000DxO

The Nikon Coolpix P6000 was measured at 5 ISO settings from ISO 100 to ISO 1600. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (100) read noise is 5.94 DN. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there.
