Query: Lasting up to 500 shots.

Depending on the subject that your shooting, and how often you turn the camera on and off between shots, having the camera do a cleaning each time it's shut off makes the big difference. If you shoot shots one by one, it will last 200-250 shots, and if you shoot all at once, non-stop, not turning the camera off after each shot, it will stretch to about 500.
