I never want the focus to change when I press the shutter release half
way.
What I do on the K10D, K20D, K3 & K1 is use the back AF button
exclusively for focus with the shutter release only tripping the shutter.
That may just be how the back AF button & AF.C work together, but I
couldn't find that explicitly stated in the manuals.
It may be that AF.S works differently.

Eric, I think John nailed the problem. You have your options set
such that the camera will not fire if [something] is not in focus.
I don’t remember the K-5 setup, but on the K-3 and other cameras
since then there is a choice for AF1 or AF2 under Button
Customization. AF1 is the “normal” approach: AF is engaged if you
depress the shutter half-way or if you press the AF button on the
back. AF2 is for we fans of “back button focusing.” If you choose
this setting, only the AF button on the back engages AF.
So, if you set your AF mode to AF-C, choose AF2 in the
Customization menu, and choose shutter priority rather than focus
priority, you can shoot as follows: 1. Press the AF button, 2. Wait
until the camera is focused on the spot of your choice. 3.
Recompose as you choose. 4. Fire away. If the subject is moving,
keep your thumb on the AF button, track along, and fire whenever
the mood strikes you. Note, if the subject is still, keep your
thumb away from the AF button unless and until you want to choose a
new focus point.
Thanks, John. Perhaps I stand to be corrected by others more
conversant with the K-5, but from my checking around in the menus and
the manual, it appears that there is no way to set shutter- or
release-priority in AF.C mode on the K-5. The options are
focus-priority it or capture-frame-rate-priority it. (Although if I
have the drive mode set for single frame shooting wouldn’t the latter
amount to shutter- or release-priority?)
