A detailed preview of the camera can be found here http://www.camcorderinfo.com/content/Panasonic-HDC-SD5-First-Impressions...
The HDC-SD5 Camera is a new Digital Camcorder that will capture to a standard SD card that you find in most Digital Still Cameras these days. This gives the Camera a great advantage in flexibility since these cards have been around for a long time now and there isn’t much chance of them disappearing anytime soon. More than this though it makes Solid State Capturing more accessible to the general public.

Solid state capturing will drastically reduce the time it takes to capture video footage to a computer. With a MiniDV camera if you have an hour of footage to capture than it takes an hour to capture that footage, with solid-state media the footage is treated like a computer file. This means that that same hour of footage could take thirty minutes or less to transfer over to you’re computers depending on the speed of media.
