Canon Powershot A710IS &nbsptype_Power & Cables The heads have a 1/4"-20The Canon Powershot A710IS is a capable "old school" point and shoot camera, with a real optical viewfinder and full manual control, powered by a pair of common AA batteries. It's got a pretty decent (for 2006) 7. 1mp sensor, optical image stabilizer, and a 6x zoom lens. It's reasonable pocketable, too. A nice little camera.
