It's directly related when shooting movies on film. In my experience the primary difference between shooting film and digital is that with film your sensor is used once and has a, (more or less), single sensitivity level, while with digital you can change ISO and you reuse the sensor. Almost everything else when shooting film applies.

Also, - what is equivalent exposure time of a video frame with K-7?
it shoots 30 FPS, so...

Is it directly related?
In principal, the actual exposure might be shorter than 1/30, and even the maximum one can be limited by something else.
