Non-Perforated film in your Leica

[elekm]

I thought most autowind cameras counted sprocket holes using a small infrared light in the film chamber. (I'm referring to the post about Canon and not referring to Leica.)

Yes you are right, those wouldnt be appropriate for IR films like HIE, but there are a few Eos's that do not, and these are the ones that are really helpful when loading in a changing bag. Any other film that is not HIE would work fine in ones that do use IR counters.

Any result on the nonperf-film-in-Leica experiment?

Hi

Dont worry it wont work, Leicia's and other reverse wind cameras use the sprocket wheel to drag the film along, the spool has a slipping clutch just to keep the film tight on the spool, no good for transport. There are some 35mm cameras that dont use the sprockets, and they can use unperforated film.

Having a Leica and putting unperforated film in it is like having a Rolls Royce and putting diesel in it.

I'd also worry about the drive sprocket teeth scraping off the occasional scrap of emulsion, which could get on the film and also clog up the works.

On Leicas and most 35mm cameras it is the sprocket wheel that turns the exposure counter. In addition the sprocket wheel is responsible for maintaining the correct interval between negatives. Therefore an unperforated film will not advance correctly.

BTW, most microfilm either 16 or 35mm is unperforated.
