EOS 5D2 Sensor Performance

ISO 1600: gain = 3.34 ADU/e-, readout noise = 2.52 e-

Gain measured with flat fields of various exposure times, assuming Poisson noise. The measured noise distributions are compared with simulations, and are indeed very close to Poisson distribution.

noise-equivalent dark at 20 deg C: 0.80 e-/sec

noise-equivalent dark at 3 deg C: 0.057 e-/sec

Dark measured with series of 10-min exposures and intervals of 10 sec. Temperature is ambient.

Linearity good to a few % when number of electrons is lower than ~6000.
