[edit] Point

Is there really any point in this article. It seems everything that needs to be said is in 8 mm film. -- Egil 14:02, 26 Apr 2005 (UTC)

[edit] Kodak Red Herring

"It was widely believed by Single 8 enthusiasts that this would offer superior film positioning, but the reality was that Super 8's plastic pressure plate could be moulded with far smaller tolerance than Single 8's metal version could be machined."

This appears to be a Red Herring from the Kodak PR department. The Single 8 system does offer better film positioning, but the flatness of the pressure plate is not the only issue.

The pressure plate in a movie camera does not actually press the film against the film gate but rather it is stopped by rails (or other stops) to form a channel with a depth slightly greater than the film thickness. So, what matters is the precision of this channel, not the flatness of the pressure plate. Actually, the film is stiff enough that the flatness of the plate makes little difference.

It should also be pointed out that the so-called pressure plate in a Super-8 cartridge is not even a flat plate.

There are other factors which include the mass of the plate, the length of the film gate, the friction between the plate and the film. design of the film claw, etc..

However, the main issue is that it is not possible to fit a film gate in the camera and a plate in the interchangeable Super-8 cartridge with as much precision as with Single-8 where they are both part of the camera.

I note that I was an assistant manager of a camera store while Single-8 was sold.
