Bits not Stops

They say the D3x has 13,7stops of DR,

Hi Bernie,

Their description uses the term "Bits" not "Stops". I couldn't find any definition on their site that defines or describes what they are doing as far as units..... There are only 10 zones and maybe 7 of those are actually useful... 13 stops is absurd... They do use something called "Tonal Range" which is different from their DR measurements and is indeed defined in f/stops.

With a DxOMark Sensor score of 88 points, the Nikon D3X takes the lead of dxomark.com ranking as of January 14, 2009. It shows very good color depth (24.7bits) and max Dynamic Range (13.7bits), with a somewhat lower Low-Light ISO value at about 1990 ISO (all 3 values in “Print” mode).

Cheers,
