Allow shutter release when focus not locked

At times I would dearly like to release the shutter when focus sas been unable to lock. After all the depth of focus at moderate apertures can more than handle the small error.
I have read the manual and searched with Acrobat as well as the original Mark I human eyeball. I give up!
Can any one please help out?

I'll check the manual properly later, but why not use manual focusing in these circumstances. This is what the manual recommends on Page 65.

You can also do that if you switch to the continuous focus option, though the risk of an out of focus image is much more likely.

Which camera???

If you're talking *ist-D/Ds/K10D etc then I have the following setup:
* In the custom menu, disable the AF-on-halfpress
* (For the K10D) make sure the custom function for the AF button is set to "Enable AF"

Then, you focus with your thumb by pressing the AF button on the back. (For the *ist-Ds it uses the OK button when you enable this mode). The shutter will always fire - even when it's out of focus.

Hope that helps!

Or, set it to "Disable AF", and hitting the appropriate button will disable the lock and let you shoot at any time.

On the K100D, it's the OK button in the middle of the D-pad.
