There was no established length of cine film in still use when
Barnack developed the Leitz camera. (To be fair, though Barnack's
camera was the first miniature-format camera to be designed and
built, it was not the first to be produced.) And there was no film
at all available: the situation when the Leitz camera began to
enter the marketplace was as it is today, with no film available at
all [he grins]. So Leitz initially supplied film in 40-exposure hot
loads for use in the estimable Leitz cassette (a design later to be
"borrowed" by Canon after the end of WWII). I honestly do not know
how we got to 36 exposures. To roughly 1960, the standard lengths
were 36 and 20 exposures, and, from then, 36 and 24. But how we
ended up with these Babylonian Base-12 lengths, I know not.

My dad used to buy 12 exposure rolls of Kodachrome- I think it was a
marketing/cost consideration.
