Hi Phil, Jack Howard here. There's a lot of ground to cover quickly, so hold tight.
Here's what I said about the K-7 in its section in the HDR All-Star Story:
The 14.6 mp APS-C Pentax K-7 is the first SLR with a true in-camera HDR processing function that captures 3 shots at +/-3 and tone maps a single JPG output image, but that’s not the reason why the Pentax K-7 made this list. Here’s the reasons: One-touch Auto Exposure Bracketing burst setting options for a 3 or 5 shot AEB burst capture at up to 2 EVs for a very wide dynamic range capture sequence in under 1 second with fast shutter speeds and DNG Raw option for instant compatibility with all HDR generation programs.
In-camera HDR captures 3 shots at -3, 0 and +3 in under a second. But with AEB can go to five shots at -4, -2, 0, +2 and +4 in under one second. You've got to combine the Max EV spacing and number of shots to get the full span.
And the K-x?
The full production K-x running FW v1.0 sitting right in front of me can AEB 3 shots at up to 3 EV spacing–the same spacing it uses for in-camera HDRI.
Please note well that NOWHERE in HDR All-Stars or other pieces I've written on the K-7 do I ever state that Auto Exposure Bracketing (not in-camera HDR) on the Pentax K-7 can be spaced at 3 EVs.
Honestly, Pentax is worlds ahead of many companies when it comes to AEB features. The most economical camera in Canon's lineup that matches the K-x AEB span is the 7D. And the 5DMII only does 3 shots at 2 EVs! Nikon has an SLR in market that doesn't even have an AEB sequence, and a handful of newer names in the photo biz totally hobble AEB sequences even in flagship cameras.
Does that make sense now?
On another note, I've started a group on Facebook about HDRI, and the forums on Christian Bloch's HDRLabs are a great source of information from my fellow Rocky Nook author.
Stop by!

PS: GormanX: In-camera HDR with these two models works best with truly wide dynamic range scenes. Otherwise, it can produce halo artifacts.

Hey Pentax Forums folks!
I just had a chance to chat on the TechTock podcast with Pentax pro Kerrick James all about his photography and his thoughts on the Pentax K-7 DSLR, and he has some cool sample shots from the art filters as well in that link.
His work is amazing, and he's great to listen to!
His list of glass is amazing!
Hope y'all enjoy it! I'm always looking for great, inspiring photographers to interview, so if you've got a lead, let me know!

The three source images are not written individually to the card when HDR Capture mode is activated. Which is why I suggest shooting the scene with AEB/DNGRAW+JPEG for source images for playing with, then switching to in-camera HDR of the same scene for maximum versatility ;)
These pre-val cameras are running V.33 and it was made clear that the higher ISO IQ is not final, so it wouldn't be fair to Pentax or their fans to comment on this at this time ;)

No video, no still images larger that 640x480 on the pre-val units ;)

Yes, it is a LDR tonemapped output image in JPEG format...
There's heaps of questions here--I'll try to answer them all in the next day or so ;)
AEB is still 5 shots for +/-2 at .3 EV spacing for max spread of -4,-2,0,+2+4 around the selected center exposure...
