Tim, this is my understanding as well. However, I want to know how much
of it goes to the dark areas (see the 9.5 EV pull out from /almost/
total blackness example) and how much of it goes to the bright areas
(remains to be seen). In particular K-7 seems to have somewhat deeper DR
in dark areas wheres in bright areas it simply sucks. Considering the
fact that Pentax do not advertise any changes in their PRIME engine, I
would hazard a guess that the bias is still similar - most of the DR
goes to the dark part of the histogram. Thus is my interest.

From my limited understanding, the higher dynamic range of the K-5
indicates a lot more headroom. I may be totally wrong about this.

Funny you should post this report, Jaume. Few days ago I had very similar
experience with my K-7 - misconfigured the flash and it did not fire in
rather dimly lit room. I had to apply a bit of Topaz Denoise (but again, I
fancy it now, 'cause it is my most recent 'toy') and the picture was totally
salvageable.
The opposite however is much more interesting. Off top of my head, K10D has
about 1 Ev (may be a bit more) of RAW headroom in bright areas. K-7 in turn
has hardly 0.5 Ev. In fact, K-7 really sucks when it comes to dealing with
bright light - minimal exposure error - total loss. I will be much more
interested to know how K-5 fares in that department. I sincerely hope it
does better than both K10D and K-7.
Oh yes, I just said that out loud - K-7 sensor really sucks.

didn't fire when it was supposed to do (it wasn't charged).
They challenged the camera for fun and were surprised by the results:
