Sony announced three HDTV camcorders that are smaller, lighter and more efficient than their predecessors. Top of the heap is Sony's first flash-based HD camcorder, the HDR-CX7 (pictured above) that Sony calls "the smallest and lightest AVCHD HD camcorder" on the market. It's so small because it's all solid-state, recording 30 minutes of its best quality 1080i video onto a 4GB Memory Stick Pro Duo. Its $1200 price is slightly better than Panasonic's HDC line of camcorders, which were the originators of this AVCHD format. Cool—Sony beating up on Panny at its own game.
