Sony has unveiled a lineup of 3 new high-def Handycam camcorders led by the HDR-CX7 which is currently the smallest and lightest AVCHD camcorder available. Weighing only 15 ounces with the battery, the HDR-CX7 can record up to 3 hours of full HD 1080 video onto an 8GB Memory Stick.

The camcorder has a 2.7 inch LCD screen which makes it easy to navigate menus and browse recorded content on the “film roll”. Recording takes advantage of a 3 megapixel sensor for HD video and the camera will take 6 megapixel still images. Both pictures and recording use Sony’s SteadyShot feature to help with the unavoidable shaky video or blurry pictures when trying to get footage on the go. The sound won’t suffer with this, either. The HDR-CX7 records in Dolby 5.1 surround sound which gets compressed and saved in the MPEG-4 file format with the HD video.

Handycam stations come with this device as well as the other two HD camcorders Sony released, and the docking stations all have a slick single “Burn” button to go along with the supplied software to make DVD creations easier. The recording media on the Memory Stick can then be played back on not only a PC, but this summer Sony expects to have a software upgrade to support playback on your PS3 game console as well.

The Sony Handycam HDR-CX7 will ship in June along with its high-def siblings, retailing at SonyStyle for about $1200.
