The Xacti VPC-HD2 is an update of the Xacti VPC-HD1, improving its CCD and light sensitivity. The HD2 will work in as low light as 12.5 lux, whereas the HD1 needed 50 lux. Other than that, it is very similar to its predecessor; it records 720p HD content on a 4GB SD card at 30 frames/second. This quality doesn't come at the expense of size or price.

The Xacti VPC-HD2 10x, 38mm to 380mm equivalent lens is mounted on the top of the camera, designed to be held in an upright position with a 2.2" LCD swiveling from out from the side. Records MPEG-4 video at 1,280 x 720 pixel resolution, can take still photos at 7.1 megapixel resolution, and connects to your AV equipment with an HDMI connector.
