What about video with zoom lenses? Pros/cons comparing to primes?
Luckily, your FA 50 will feel like a new lens on the K-7--focusing is so much faster!
For video, you don't really need the sharpness of a prime so zooms are just fine, but primes are more fun for playing with DOF.
There's some K-7 video done with the FA 50 and the DA 21 here (and it's pretty incredible):

Any of those zooms you mentioned would be great for the wide stuff. I've only used the DA*16-50, and it's great (especially stopped down--wide open it has some field curvature which prevents everything in a flat plane from being in focus). I've heard great things about the Tammy 17-50 and I've used the Tamron 28-75, which is also a very nice lens.
