It was actually announced a few days before CES even got started, but Samusng's new camera and lens combo is one of the most interesting developments of the entire show. The camera itself looks promising, with an APS-C sensor, a slick new body design, and the ability to shoot 1080p video at 60 FPS. But, the lens is where the really cool tech kicks in.
In 2D mode, operates like a traditional 45mm lens. In 3D mode, though, a pair of LCD shutters inside the lens alternate open and closed, very similar to the way their active shutter 3D glasses work. By capturing alternating frames from slightly different angles, you're able to get true 3D 1080p video from a single lens.
We actually saw the footage up close on a Samsung 3DTV and it looks impressive. And since it's a full-fledged 2D lens as well, buying isn't as much of a risk as past 3D lenses like the one made by Panasonic.
