The 12.2 stops quoted by DxO is measured at base iso??? but the cambridge colour site states:
Technical Note: In some digital cameras, there is an extended low ISO setting which produces less noise, but also decreases dynamic range.
Why would DxO test at base iso if this is true? The chart at DXO doesn't state it is tested at base iso and I think that testing at base iso wouldn't give a true test result.
