he Panasonic AG-HMC40 is a camcorder designed to record in high definition on standard Secure Digital (SD) and SDHC memory cards. The camera is extremely portable and lightweight, weighing in at just over 2 lbs. While SD-based camcorders have been gaining ground in the consumer market, the AG-HMC40 has the ability to record AVCHD images at significantly higher bitrates. This enhancement makes the camera's codec more efficient than comparable HD interframe codecs, such as HDV and XDCAM EX. Using H.264 as its compression algorithm the camera can record incredibly detailed images at a fraction of the file size. The handle is detachable and can hold an optional XLR audio system.
