Focus trap on K20D?

I am trying to get the focus trap method to work on the K20D, without success yet.

On the K10D, when putting a manual focus lens on the camera and setting AF mode to AF-S, I could focus at a given distance and fully press the shutter button. The K10D took the photo as soon as there is something sharp within the focus area.

This seems somehow not to work on the K20D. The photo is taken immediately.

Does anyone know how to get the focus trap method to work on the K20D?

It is everything in the manual...

- set custom function 34 "Catch-in focus" to 2
- put either manual lens on camera or a DA* with AF/MF switch set to MF
- AF mode on AF-S
- focus on any distance and press the shutter, as soon as something is within the focus area, the photo is taken...

So for this mode you either have to have a manual focus lens or additional AF/MF switch on lens whitch DA*s seem to have. Right?

Yes, that is correct, a manual lens or an AF lens with an AF/MF switched.

I did the test with a Voigtlander 125/2.5 manual lens and also with the DA*16-50 which needs to be set to MF.
