Kevin Carter has just posted a full review of the newly released Canon EOS-1D X Mark III ( Amazon/ B&H/ Adorama) at the DxOMark.com. Canon EOS-1D X Mark III sensor achieves a total score of 83, which puts it at the 47th place in all the full-frame and MF sensors.

Although we at DXOMARK test only sensor performance and no other features, at face value it’s an incredibly fast DSLR with not only blazing AF speed, incredible continuous shooting rates and a prodigious buffer, but also an equally impressive sensor.
