Nikon 1 V3 vs Nikon Coolpix P1000: read noise comparison
Input-referred read noise at base ISO: Nikon 1 V3 12.6 e⁻ (ISO 160), Nikon Coolpix P1000 2.5 e⁻ (ISO 100).
Nikon 1 V3
The Nikon 1 V3 was measured at 7 ISO settings from ISO 160 to ISO 6400. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (160) read noise is 4.14 DN, or 12.6 electrons at the sensor. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 11,900 electrons; unity gain is around ISO 490.
Nikon Coolpix P1000
The Nikon Coolpix P1000 was measured at 7 ISO settings from ISO 100 to ISO 6400. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (100) read noise is 1.92 DN, or 2.5 electrons at the sensor. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 5,039 electrons; unity gain is around ISO 130.
