Nikon 1 AW1 vs Nikon 1 J4: read noise comparison
Input-referred read noise at base ISO: Nikon 1 AW1 16.7 e⁻ (ISO 160), Nikon 1 J4 10.9 e⁻ (ISO 160).
Nikon 1 AW1
The Nikon 1 AW1 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 6.15 DN, or 16.7 electrons at the sensor. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 3200 don't change analog gain (digital push). Full well at base ISO is about 11,141 electrons; unity gain is around ISO 430.
Nikon 1 J4
The Nikon 1 J4 was measured at 8 ISO settings from ISO 160 to ISO 12800. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (160) read noise is 3.53 DN, or 10.9 electrons at the sensor. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 6400 don't change analog gain (digital push). Full well at base ISO is about 11,952 electrons; unity gain is around ISO 490.
