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.
