Panasonic upgraded its pro video lineup in large fashion at the NAB media show with new camcorders, displays, and storage. Heading up the group is the AG-HPX600, what it calls the lightest-ever shoulder-mounted camcorder at under seven pounds. The camera also touts a new 2/3 CMOS sensor and is even upgradeable to add features like AVC-Ultra support, wireless metadata, recording by proxy, and variable frame rates.
