ABSTRACT:
A multi-format camera is provided for taking pictures in several different sizes, such as 21/4.times.15/8 ins. and 21/4.times.23/4 ins., on separate rolls of similar length film. A plurality of roll film holders for the different picture sizes have respective coded means representative of the different picture sizes and respective metering assemblies for metering the roll film over the film holders 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 code responsive means for determining the effective size of a variable size exposure area in accordance with the picture size coded on a film holder received in the camera. A single drive gear is positioned in the camera for engagement with the gear member of the metering assembly on a received film holder, and manual or automatic means rotates the drive gear between exposures to advance roll film in the particular length increments determined by such metering assembly.
