Panasonic has launched a couple of new camcorders claimed to be the lightest in the world weighing only 0.5 pounds. The camcorders are the HDC-TM10 and the HDC-SD10. The only real difference between the two is that the SD10 stores video to SD and SDHC cards only. The TM10 has 8GB of internal storage and then changes to SD/SDHC cards. The cameras feature 16x optical zoom. They also come with advanced optical image stabilization to minimize shake at high zoom levels. Both cameras have 1080p resolution video. Navigation is done with the help of a touchscreen. The SD10 will cost you US$ 549.95 and the TM10 will be US$ 599.95 and will be available from September.
