Canon EOS M10 read noise vs ISO
The Canon EOS M10 was measured at 9 ISO settings from ISO 100 to ISO 25600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (100) read noise is 9.06 DN, or 16.6 electrons at the sensor. From ISO 3200 up the camera is effectively ISO-invariant: raising ISO further doesn't meaningfully lower shadow noise. Full well at base ISO is about 26,350 electrons; unity gain is around ISO 180.
