Panasonic today brought two camcorders to the US that it believes set records. Both the SD10 and TM10 are deemed the lightest cameras to record 1080i in AVCHD (H.264) and each weigh exactly half a pound. Aside from being more comfortable to hold, either has a relatively long-range 16X zoom and an advanced optical image stabilizer that specifically extends the effect when the user is on the move.
