This is not my experience at all.  Any 'electronic' camera I have ever
used flashes an 'E' and locks up if the film wont load.  (MZ-30, MZ-S,
mjuii, Ixus etc)

Also, I have noticed on the MZ-S that when the film is finished and
rewinds you cannot fire the shutter again until you open and close the
back.
