Sure, - but that's for when you are doing a "planned" shooting, and when
you have a VIDEO camera, i.e. a camera that is designed (as opposed to
_adapted_) for shooting videos. I don't know about K-3, but K-7 and K-5
are not in that league.

In my case, Bruce has correctly identified the situation:

While K-5 cannot do AF in video mode, and that's what you have to do
manually, it does a reasonable job on doing metering...
... but only in the center-weighted (and maybe "matrix") mode for the
reasons described in the original message.

Videos I shoot are more close to "snapshots" then to anything more
serious.  (You can see some of them here: http://youtube.com/SwingStR
For most of the occasions, I just don't have time/energy to 
do it in a more proper way (with a tripod, etc.).
Besides, as far as I know, K-5 doesn't allow to change the aperture
_after_ you start recording the video.
AFAIR, the only option about that is to allow or not to allow camera 
changing the exposure during recording (I suspect it does that but
adjusting the gain, - essentially the equivalent ISO).
