Possibly a problem with the lens or it's contacts?
Will the camera make an exposure with the lens not fitted?
If so it could be that the camera "thinks" that the lens is not set to "A" on the aperture ring, but of course, the "kit" lens doesn't have an aperture ring!
A work-around may be to go into the ' Custom Setting' menu and set 'Using aperture ring' to "2" ... no guarantee this will work, but worth a try.
If these diagnoses give some kind of result, maybe the lens and/or lens mount contacts need cleaning. Unfortunately I don't have a problem with my *
ist DS so I can't replicate the symptoms exactly. FWIW I use eneloop batteries in my
*ist digital cameras and they are totally reliable
Good luck
