FujiFilm X100T vs FujiFilm X100VI: read noise comparison

Input-referred read noise at base ISO: FujiFilm X100T 3.6 e⁻ (ISO 200), FujiFilm X100VI 2.5 e⁻ (ISO 125).

FujiFilm X100T

The FujiFilm X100T was measured at 16 ISO settings from ISO 200 to ISO 6400. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (200) read noise is 1.52 DN, or 3.6 electrons at the sensor. From ISO 800 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 2500 don't change analog gain (digital push). Full well at base ISO is about 36,845 electrons; unity gain is around ISO 480.

FujiFilm X100VI

The FujiFilm X100VI was measured at 26 ISO settings from ISO 64 to ISO 51200. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (125) read noise is 1.61 DN, or 2.5 electrons at the sensor. From ISO 2500 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 12800 don't change analog gain (digital push). Full well at base ISO is about 24,053 electrons; unity gain is around ISO 200.
