Canon EOS 60Da vs Canon EOS 6D: read noise comparison

Input-referred read noise at base ISO: Canon EOS 60Da 14.2 e⁻ (ISO 100), Canon EOS 6D 23.9 e⁻ (ISO 100).

Canon EOS 60Da

The Canon EOS 60Da was measured at 20 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 5.98 DN, or 14.2 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 6400 don't change analog gain (digital push). Full well at base ISO is about 33,926 electrons; unity gain is around ISO 240.

Canon EOS 6D

The Canon EOS 6D was measured at 28 ISO settings from ISO 50 to ISO 102400. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.

At base ISO (100) read noise is 4.89 DN, or 23.9 electrons at the sensor. From ISO 5000 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Settings above ISO 25600 don't change analog gain (digital push). Full well at base ISO is about 69,959 electrons; unity gain is around ISO 490.
