The Actionsampler flash camera uses the same much-loved four-shot set-up of the traditional Actionsampler, plus an extra four-step sequential flash. With one push of the shutter button, all 4 lenses fire in ideal synchronicity with the rapid-fire flash: all this takes 1 second, with an Approx. 0.25 second between each frame. Flash at night to reveal important action at parties, concerts, & night-time events. Flash in the day to fill in those highlights. This camera uses standard 35mm film & standard processing. It is powered by two AA batteries; approximate recycle time is 7 to 10 seconds.
