Panasonic has introduced what it claims it the lightest shoulder-mounted camcorder ever created. Weighing in at under seven pounds, the AG-HPX600 is very user-friendly for videographers who need to hold cameras for long periods at a time. But just because it's small doesn't mean it doesn't pack a punch. The AG-HPX600 is outfitted with a lot of the latest technology. It's also outfitted with a huge price.
