Sanyo on Thursday introduced the Xacti HD1000, which it bills as the world's smallest and lightest full HD digital camcorder. The Xacti HD1000 writes video to an SDHC memory card and can record in 1920-x-1080 pixels. It ships in September in the US for $799.99. UK pricing and availability has yet to be announced.

The Xacti HD1000 weighs 9.5 ounces and, like other Xacti camcorders, features a pistol grip-style design, but it sports new ergonomic elements the company developed in conjunction with Japan's Chiba University, to make it comfortable to hold for long periods.

The camcorder records MPEG-4 AVC/H.264 video, and can squeeze 85 minutes of 1920-x-1080 video onto an 8GB SDHC memory card. Users who reduce quality to 640 x 480 can get up to 5 hours, 14 minutes on an 8GB card. It can also record four-megapixel digital still images.

Other features of the Xacti HD1000 include a 10x optical zoom lens, 2.7-inch widescreen LCD display, HDMI output, image stabilization, "face chaser" function for still images and more. It connects to a Mac or PC using USB.
