Re: Dry firing (was: Silicon film, etc)

The only modern camera that I've experience with that sensed weather the film
loaded or not is the zx-m.  If film is loaded and it isn't advancing the 
shutter
still fires, the camera just doesn't count frames.  If I remember correctly 
this
is consistent with many other older model cameras that I've handled.  Even 
in this age
where camera manufactures try to idiot proof everything the cost of doing 
so would
be prohibitive.  Most cameras will probably set the correct aperture and 
shutter speed
and auto focus regardless of correct film insertion.   (Those few that did 
fail to fire
without film could be fooled by a cardboard insert,  many came with one).

Surely the (correctly loaded) presence of film is detected by
the toothed wheels to the right of the film gate?  If these turn
when the advance motor is working, film is loaded and the camera
will fire.  If they don't, the film is misloaded or not present
and it will not.

I don't see how the insert will overcome this.  It will be much
easier to deal with those units which use LEDs to monitor film
movement.

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.

Now that's an interesting question.  I'm not able to do any
direct research since I don't own any other ZX models.

  However I can deliberately mis-load the example of the ZX=M I
  own and it
  will fire
  and advance even though there is no film movement.  Since
  this camera is
  based on
  ZX series I would bet that all other ZX/MZ cameras with the possible
  exception of the
  MZ-S will work the same way.

I wonder...  I am pretty sure my MZ-30 will not work if it misloads.
Looking at the cameras, the MZ-M and MZ3/5 look like one family while
the MZ-30, MZ-7 and MZ-6 look like another.  The former models look to
only have a frame counter LCD, whereas the latter show much more and an
'E' flashes for a misload.  I wonder if one family or MZ/ZXs handles
this differently to the other?

I will test properly with my MZ-30 tonight.  Although I am sure I have
had a misfeed in the past, I cannot state categorically this is the case
without verification.
