Sony a5000 vs Sony QX1: read noise comparison

Input-referred read noise at base ISO: Sony a5000 5.3 e⁻ (ISO 100), Sony QX1 5.3 e⁻ (ISO 100).

Sony a5000

The Sony a5000 (ILCE-5000) was measured at 23 ISO settings from ISO 100 to ISO 16000. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (100) read noise is 2.57 DN, or 5.3 electrons at the sensor. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 10000 don't change analog gain (digital push). Full well at base ISO is about 32,589 electrons; unity gain is around ISO 210.

Sony QX1Twin

The Sony QX1 (ILCE-QX1) was measured at 23 ISO settings from ISO 100 to ISO 16000. This model has no measurement of its own; the Sony a5000, which uses the same sensor, is shown.

At base ISO (100) read noise is 2.57 DN, or 5.3 electrons at the sensor. From ISO 400 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 10000 don't change analog gain (digital push). Full well at base ISO is about 32,589 electrons; unity gain is around ISO 210.
