IDG News Service - Two days after unveiling in the U.S. what it said was the smallest high-definition video camera in the world, Matsushita Electric Industrial Co. (Panasonic) took the wraps off an even smaller camcorder last week.
The HDC-SD7 measures 52 by 110 by 87mm, giving it a volume of 330 cubic centimeters -- that's smaller than the 375cc of the HDC-SD5 that got its international launch earlier. It weighs 350 grams with the battery and memory card against 400 grams for the SD5.
The two cameras look very different. Unlike the SD5, which is longer than it is tall or deep, the SD7 is taller than it is wide or long, so it has the appearance of being held vertically.
They have almost identical technical specifications. Both pack 3CCD (charge coupled device) sensors behind a 10X zoom lens and have a 2.7-in. widescreen LCD monitor.
One of the secrets to the small size is the use of an SD memory card as a recording medium. The electronics and socket needed for a flash card takes up much less space than a DVD or hard disk drive and thus contribute to the size and weight savings over other high-def models.
Both record full HD (1,920 by 1,080 pixels) MPEG4 AVC/H.264 video at a range of quality levels. At the average 9Mbit/sec. rate, a 4GB SD card can hold up to 60 minutes of video, said Panasonic.
The cameras will both cost around $1,175 when they go on sale in Japan. The SD5 will launch on Aug. 25 and the SD7, which will only be available in Japan, will hit shelves on Sept. 8.
