OK thanks. I wasn't implying your intentions were not of good intent, I was just curious about the F100's internal link that was connected to the problem
I don't have an F100 but in none of my cameras is there this link to frame counting and refusal to take the film further than frame 30
I can see why without a DX code a camera has to revert arbitrarily to say an ISO of 100 this rendering a problem with exposure if the owner doesn't set the speed dial correctly for the film but stopping the film at frame 30 just doesn't seem to be likely link. If it makes sense to Nikon to build in a mechanism to prevent wrong exposure by not allowing the film to be used then I wonder why it doesn't stop the film at the start
None of it makes much sense to me if the F100 does what you think it does
Can any other F100 user chime in here to help settle the matter?
