A microfilm magazine having a light tight cover with a single central fastening which has controlled pressure means, the fastening being secured to and stabilizing the film supporting shaft. The film passes through a short minimum contact path and leaves the magazine through an opening fitted with a normally closed light tight door, which opens automatically when the magazine is inserted in a camera. The door and the film footage follower arm are latched clear of the film for loading, the latches being automatically released when the cover is applied. A constant load clutch controls the film reel rotation and the drive means is biased to permit safe assembly into a camera when the drive gears are misaligned.
