I think it fair to say that every camera brand has it's fair share of strengths and weaknesses, but IMHO this faux-pas on the part of the Pentax K7 design engineers is simply unforgivable, particularly given the negative feedback they must have received about the dark-frame subtraction shortcomings of the K20D. This was an entirely preventable issue and I am extremely disappointed that Pentax have failed to address it satisfactorily with the new model.

I think Pentaxians (myself included) can sometimes get defensive because of the number of people that seem to spend a good portion of their time telling everyone why they should buy Canon/Nikon gear. Maybe someone that hangs out on the Canon forums can provide perspective - Do people frequently show up in the Canon forums and tell all the Canon users to switch to Pentax? Do people spend a lot of time telling Canon users how Pentax users get SR with their awesome prime lenses? I suspect - although I do not know since I don't belong - that this doesn't happen very often.
Not an excuse, I know. If you have issues with the way Pentax operates their cameras, by all means, air your complaints; you have every right, IMO. I think when you start talking about Canon or Nikon "doing it right", you gotta expect some knee jerk...
Of course, nostatic also has the right to *say* "If you don't like it, go buy a Canon", as you have the right to not do so.
Now - I seem to remember, long ago, way back in the mists of time, dealing with reciprocity failure at long ( more than five seconds or so ) exposures. I seem to remember that at sixty seconds or more, it was a full stop on Ektachrome 100.
Not that I think you *shouldn't* be able to disable DFS; it *is* just a firmware setting, although one might discover that the Pentax engineers knew what they were doing because the resulting images might be useless.
I'm curious, though, how a software package can do DFS, since it can't create a dark frame exposure post-hoc.
