I think your problem is that you are in AF-A mode (shooting in Auto Pict mode) This allows the camera to choose between AF-S and AF-C mode according to what's appropriate for the scene mode.
Try switching to Av or P mode, and make sure it's in AF-S. You should not be able to take a pic unless the AF system indicates an in-focus subject. CIF should then work as expected with your manual focus K mount lenses.

Hi Scott, I have been trying every mode systematically in an attempt to get this working but mostly in Aperture priority or Manual mode so I don't think its AutoPict causing the problem. Definately in AF-S mode in the menu but as I said earlier, it does display as MF when looking in INFO.
Originally posted by ultraviolet My K-x does work both AF-S and AF-A but not with AF-C. If you are using M, K, A series lens (i, e K mount), no shorting necessary (already done by the lens) but if you are using M42 lens and using original adapter then you have to short with aluminum tape or similar. And M mode is also ok with CinF, not just Av (for non auto aperture lenses all modes are Av mode but M). Everything you have done so far are all correct steps.
Just in case any other setting is interfering, what you can do is 1) reset all coustom function (Menu C4). Now change only two thing 1) Allow Aperture ring (C4-22) and 2) Catch-in-Focus 2 (C3-21). {I just did it to check}, Keep the Camera setting same as before (ie, AF-A or AF-A).
*Info will show MF, I used a K55/1.8 to test.
If it does not work you have contact shorting problem. As suggested by Jeff, cleaning might help. If the kit lens work properly, then it must be the lens mount, clean that carefully. Good luck? No you do not need good luck for CinF on a Pentax camera

Hi Ultraviolet,
Using 2 different manual lenses as previously mentioned. I have cleaned both and also the mount and contacts on the camera. When I say 'clean' they aren't or weren't exactly dirty! I didn't get any residue off to speak of and they aren't marked, corroded or in the least bit visually stained or 'dirty'. If by cleaning we are talking chemicals, I haven't done that.
I reset everything in the custom menu back to default and just had C4-22 and C3-21 enabled as suggested. Used exactly the same scenario which is to point at a subject, make sure it is really out of focus. Press shutter all the way down and at this point the shutter is released and I have a very out of focus picture.
The camera seems to work fine in all other respects but I'm starting to think CiF is a function that isn't going to work on my camera with either of my 2 K mount manual lenses.
My frustration is that we think we are about to have a litter of hedgehogs appear in our greenhouse and I was desperate to try and capture some images of them coming out their nest for the first time without spooking them too much.
Thanks for everyones help, it has been greatly appreciated.
David
