But I insist, the DxO criteria (0dB) is useless for someone who wants to take a picture of a given DR.

I certainly do not have the competence to contradict you It would be nice to see a "real world" comparison of what a higher DR can do for us.

Basically two things:

  • Being able to capture detail both in the highlights and shadows of high dynamic range scenes in a single shot. Just to make an idea, any interior room with a window open outside to a sunny day is at least 12 stops. In my calculations the K5 captures 11,2 stops.

  • Being able to make mistakes in exposure (typically strong underexposure), and still have decent images.

Examples:
