Canon PowerShot SX60 HS vs Canon PowerShot V1: read noise comparison

Canon PowerShot SX60 HSDxO

The Canon PowerShot SX60 HS was measured at 6 ISO settings from ISO 100 to ISO 3200. Values were derived by Bill Claff from DxOMark lab data.

At base ISO (100) read noise is 2.68 DN. From ISO 1600 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise.

Canon PowerShot V1

The Canon PowerShot V1 was measured at 27 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 2.50 DN, or 4 electrons at the sensor. From ISO 20000 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 25,725 electrons; unity gain is around ISO 160.
