Sanyo has launched the Xacti HD700, a pocket-sized, 720p high-definition digital camcorder, and, as is becoming

, it's the world's smallest and lightest.

The little brother of the previously launched HD100, the HD700 is capable of recording both 720p-quality high-def video and 7.1-megapixel photos to an SD or SDHC memory card.

With an ultra-compact, ergonomic shape, the HD700 is angled at those shooting for web use - video is recorded in iPhone and YouTube friendly MPEG4 AVC/H.264 format.

A quick run down of features reveals "Face Chaser" which does what you'd imagine, 5x optical zoom and a 2.7-inch screen.

The SANYO Xacti HD700 will be available in silver, red and brown in the US at the end of October for $600 with no info as yet on UK/Euro pricing or availability.
