The instructions I came up with for a K100D for taking photos with a manual lens as long as an object is in focus have a few more steps:
------------
Mode Dial > M
Record Menu > AF Mode > AF-S
Record Menu > Swtch dst msr pt > Center Spot (may be greyed out)
Setup Menu > Auto Power Off > OFF
Custom Menu > Using Aperture Ring > Permitted
Fn Button Menu > Drive Mode > Continuous
Front of camera slide switch > AF
Rear of camera slide switch > SR Off
I used external power since the camera was left on for over an hour.
Focus camera at desired distance.
Aim camera slightly away from any background objects at the focus distance.
Lock shutter with remote shutter cable or shorting plug.
Test by passing your hand slowly through focus point.

I used this procedure when aiming the camera to one side of a squirrel feeder. I came back later and had 900 photos and most had a squirrel in focus.
