The following is a video clip of Panasonic AF100/105 Micro Four Thirds camcorder from 2010 IBC. [HT Engadget – Panasonic announces AF105 Micro Four Thirds camcorder, interchangeable lenses not included]
May 13, 2011 Update: Here is a great video tutorial of AG-AF100 given by Panasonic Product Manager, Jan Crittenden-Livingston.
Note: A SDHC Class 6 memory card is sufficient to do variable frame rate stuff (at the best quality). A class 4 is sufficient if variable frame rate is not needed.
