Various sources list the Canon 1000D shutter life expectancy at between 25,000 and 100,000 activations. If the 8mm film is 16 frames per second, then this setup should be able to capture between 26 to 104 minutes of film before consuming the expected lifespan of the camera shutter.<p>Edit: Changed math from 24 frames per second to 16 fps to reflect the 8mm film fps standard playback speed of 16 fps.
