I remember I bought a compact samsung in the early nineties that had this feature. I would set it to take a snapshot every thirty minutes and mount it on a tripod and turn it off. Every 30 minutes it would spring back to life, the lens extends and it takes a shot and then the lens retracts back and it shuts itself off waiting for another 30 minutes to elapse before doing the same thing again. It was a nice feature that I put to use maybe once or twice! If it also had anti-theft alarm it would be setting now at the back of my camera closet.
That's a feature all camera's should have, especially pro ones... for stop motion etc, I've never understood some of the things the pro models leave out... it's sad and amazing how stupid some of the companies are.
