A multi-format camera is provided for taking pictures in several different sizes, such as 21/4x15/8 ins. and 21/4x23/4 ins., on separate rolls of similar length film. A plurality of roll film holders for the different picture sizes have respective frames for carrying the similar length rolls and respective metering assemblies for advancing the film over the frames in different length increments corresponding to the different picture sizes. Each of the metering assemblies has at least one gear member situated at the same location on the film holders. The camera includes a single drive gear positioned for engagement with the gear member of the metering assembly on a film holder received in the camera, and manual or automatic means for rotating the drive gear between exposures to advance roll film in the particular length increments determined by such metering assembly.
