Every model also incorporates K2, a technology developed and used in professional sound studios, which is applied during playback (GZ-E100) or during recording (all other models).
Five models are shipping in late December that include two with remote control: WiFi on the 16GB GZ-EX350 and 32GB GZ-EX370 lets a nearby Android phone or tablet steer the camera from a distance, and the camera itself can wirelessly back up its footage as well as share media through WiFi Direct.
