Both the K-5 and the K-1 do live view with no lens attached.
However.... if you mount a lens on a K-5, put the camera in LV, and then dismount the lens, the K-5 pops out of LV mode. The behavior occurs with both newer lenses (with the multi-point contacts) and older manual lenses that just have a conductive mount ring. A loose lens and intermittent contact between the K-5 and lens will cause erratic LV behavior.
EDIT: The K-1 is a bit different... It will go into LV mode with or without a lens. But it does not drop out of LV mode if you dismount the lens.

This is probably the problem.
If the Exakta mount is not very conductive or is a bit loose, the lens will lose electrical contact wit the camera. The camera will think the lens was removed and drop out of LV mode to protect the mirror, shutter, and sensor.
As for the exposure issues with an ND filter, that can occur if you meter through the lens but don't have your eye or the little plastic shield covering the viewfinder eyepiece. Light can come in through the eyepiece and fool the meter.
