Hi!
DXOMark
(http://www.dxomark.com/index.php/en/Camera-Sensor/All-tested-sensors/Pentax/K5)
publishes that K-5 has 14.1 EV of dynamic range. My understanding
thereof is that its sensor can tell apart 2^14.1 different shades which
although close but slightly bigger than 14 bit RAW as per Pentax own
specification.
I realize that dynamic range is not the same as how many useful bits of
data per pixel RAW format contains. However, given that both are scales
of powers of two, it would seem to be interesting to consider which part
of these 14 bits (or 14 EVs) corresponds linearly to one another.
As a side remark I think it is very odd that one is bigger than another.
Few examples to point:
Phase One P65 Plus - 16 bit RAW, 13 EV of DR
Leica M9 - 14 bit RAW, 11.7 EV of DR
Nikon D3S - 14 bit RAW, 12 EV of DR
What do you think?
Thanks.
Boris
