The Panasonic HDC-SD1 camcorder is perhaps the most remarkable entry into the new class of high-definition camcorders, with advanced HD capabilities that will bring a cinematic level of detail to your home movies. For one, the SD1 is so-named because it records video directly to Secure Digital memory cards. Solid state flash memory. There are no moving parts involved in the recording process, which means there's less stuff that can get broken and ruin your camcorder or your recording. Top it all off with a really amazing zoom microphone that follows the lens and can capture excellent sound and great distances, and you've got a really wonderful camcorder.
