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).

RE: Dry firing (was: Silicon film, etc)
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. -Original Message- From: Peter Alling [mailto:[EMAIL PROTECTED]] Sent: 19 September 2002 16:29 To: [EMAIL PROTECTED] Subject: 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.

RE: Dry firing (was: Silicon film, etc)
Now that's an interesting question. I'm not able to do any direct research since I don't own any other ZX models.

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?
RE: Dry firing (was: Silicon film, etc)
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. -Original Message- From: Peter Alling [mailto:[EMAIL PROTECTED]] Sent: 19 September 2002 17:49 To: [EMAIL PROTECTED] Subject: RE: Dry firing (was: Silicon film, etc) Now that's an interesting question.
