It's called the Dual because it's set up to shoot both full HD movie clips and 12-megapixel stills. Movies can be captured at 1080p at 30 or 60 frames per second (H.264) and it can also do high-speed capture at up to 240fps at 720p resolution for slow-motion clips.
As a still camera, its backside-illuminated sensor allows for faster shooting and better low-light image quality. It has an f2.6 wide-angle lens--26mm for photos and 31mm for video. Plus, there's a built-in Xenon flash to help brighten your shots.
One of the key features of its predecessor, the excellent Zi8, was its mic/headphone jack and, thankfully, that returns on the Dual. It also has a Micro-USB port for transfers and charging, Micro-HDMI for connecting to an HDTV, and an SDHC card slot for storage.
On the right side/top are discrete controls for photos (the sample I played with focused and shot faster than most minicamcorders I've tested). On back next to the 3-inch high-res LCD are the remaining controls including a one-touch video record button and Kodak's Share button for in-camera tagging for uploads to sharing sites and e-mail. The Dual has a nice-looking updated interface, too.
I actually got to see a sample of the video quality and if what I saw is indicative of the final product, this could be the first minicamcorder to actually be as good as a full-size camcorder. Of course, the big downside is the lack of a zoom lens; all that's available is an improved 4x digital zoom.
Look for the Playfull Dual in February for $199.99.
