Hrm, assuming you're measuring from the K-7's tightest spot, however much that sticks out, one of those might just squeak by on a K20d.
I've been wondering.
Anyway, as far as being in a hot place, well, that's just an exacerbating factor: keeping any sensor running is going to make heat, and it's got to go somewhere: the hotter the ambient air, and possibly the more humid, it's just that much harder to dissipate it.
It's one of the reasons, actually, I was in the 'Who cares about video' camp: I wouldn't be willing to put too much of that kind of wear and tear on the machine, considering how long it might have to last me.
