Leica S (Typ 007) vs Leica S3: read noise comparison
Input-referred read noise at base ISO: Leica S (Typ 007) 6.1 e⁻ (ISO 100), Leica S3 5.9 e⁻ (ISO 100).
Leica S (Typ 007)
The Leica S (Typ 007) was measured at 8 ISO settings from ISO 100 to ISO 12800. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (100) read noise is 1.88 DN, or 6.1 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 6400 don't change analog gain (digital push). Full well at base ISO is about 52,703 electrons; unity gain is around ISO 320.
Leica S3
The Leica S3 was measured at 10 ISO settings from ISO 100 to ISO 51200. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (100) read noise is 2.46 DN, or 5.9 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 39,621 electrons; unity gain is around ISO 240.
