Also the use of Optical DOF is interesting.
I do not have the ISO set to automatic, ever.
However, even trying all these things, I don't understand why there seems to be no settings to do the following.
Mount a Pentax K or KA lense.
Set the aperture using the lens aperture ring.
Set the shutter speed using the e-dial
Press the shutter button to take a photo
...and the shutter speed remains where I left it. This does not happen with any of the settings I have tried.
I just want the camera to do what I tell it and not try to be 'helpful'. Very annoying.
Thanks again.

What happens if you this: mount a
KA lens. Set the aperture ring to A
Set the Mode dial to M.
Set the aperture with the rear dial.
Set the shutter speed with the front dial.
Set the iso to anything but Auto.
Take a picture.
Do you get the same result, that is, does the shutter speed (or {in this case as the aperture is set through a dial} the aperture) change from your original setting?
" In addition to this if I press the green button to stop down it chooses a shutter speed for me. Once again when I take the photo the shutter speed often changes."
If you use the green button a shutter speed is set and after taking the picture the lightmeter indicates the shutter speed and again you have to push the green button to properly setting the shutter speed. So the changing of the shutter speed directly after using the green button is normal behaviour. I tried this out on different Pentaxes, They all work in the same way.
