I think there was a Leica cassette that would open when inside the camera to
allow the film to pass but- the inside of the camera in some way
mechanically coupled with this special cassette to open it when it was
inside and the camera was closed, I don't think it can be used in "normal"
cameras. So it's not much use unless you use the requisite Leica rangefinder
body- maybe they also fitted certain Contax or Nikon rangefinder bodies- I
can't remember now. The LUG was where I read this- I just wish I'd been
paying attention!- then I'd know which bodies this applies to. I think these
cassettes are still around on the used market, as are old Leica bodies.
Hmmm. I just looked in my M4-2 and the catch for the removable baseplate has
one part that appears to grip the camera body to hold the base on, which
engages as you turn it, and then there's another bit, that goes slightly
higher up into the body and turns at the same time, which appears to hold
the casstte in place, and- to turn something that is projecting from the end
of the cassette! Maybe that is the part of the camera that opens a Leica
cassette. All of which is very interesting, but I think you still have to
have the fiom leader sticking out to start with in order to thread the film
into the camera when loading, and therefore the same problems of IR light
entering will presumably still occur to some extent.
