A film transport unit for use as a microfilm camera, or the like, and having quick release means for attachment of a variety of standard film magazines. Film is drawn from the supply magazine and a supply loop is maintained by a drive which grips only the edges of the film, and is advanced incrementally through an exposure gate by an edge gripping capstan driven by a stepping motor. The film loading path is very simple and the guiding elements incorporate means for maintaining constantly precise film advance over long periods of use, without damaging stresses or wear on the film.
