The fine group at DCresource has a review on the Casio Exilim EX-Z850 where they state, 'The EX-Z850 is a compact metal camera with an 8.1 Megapixel CCD and 3X optical zoom lens. While not the smallest camera out there, it's still compact enough to go anywhere that you do.' 'The Exilim EX-Z850 has a very good movie mode. You can record video at 640 x 480 (30 frames/second) with sound until you run out of memory. That takes just 16 seconds using the built-in memory, so you'll want a decent-sized memory card for longer movies (a 1GB card holds more than 30 minutes).'
