The Sony PMW-EX3 is a flash-memory based high definition camcorder capable of a variety of frame rates and resolutions using Sony's new XDCAM-EX intraframe codec. A "big-brother" to the PMW-EX1, the PMW-EX3 ups the ante by providing an interchangeable lens mount. The mount allows users to put a variety of professional lenses on the camera, including 1/2" and 2/3" bayonet mounts (with optional adapter).
