Dear readers,
I'm considering to buy a linhof technika III version 5.
The camera has a 127mm lens, a bellow with a minor light leak ( can be replaced ), a viewfinder and eight 9x12cm backs.

My doubts in the camera are not in the availability of suitable lenses and cams, but I don't know if the old 9x12cm film is still so widespread.

Are there alternatives? for example is it possible to use the old linhof technika III, 5 with 4x5 inch holders? And what brands of film suit to the classical technika III holders?
