It happened again yesterday, with the DA* 300.
Re-engaging the lens with the body by a small rotation had zero effect.
Trying changes to AF switches , mode, etc made no difference, so switched off and back on again.
The camera took a few seconds to power up, maybe 3 or 4, again very similar to the delay in power up after a battery change.
I'm now suspecting it is a battery/power issue.
The battery was showing full and the exif from a shot shortly after the incident shows "Body Battery State : Close to Full". I use Pentax batteries.
I've had a close look at all the lens contacts and they are as they should be.
I'll try cleaning the contacts again.
Cheers,
Terry
