JVC just announced a handheld 4K camcorder that it claims is the first of its kind in the world. The GY-HMQ10, as it is known, features a 1/2-inch CMOS sensor with a staggering 8.3 million pixels. Video is recorded at a native resolution of 3840 x 2160 with frame rate options including 24p, 50p, and 60p. Even more impressive, the company's high-speed Falconbrid LSI chip allows 4K images to be mirrored on a projector or external monitor with nary a hint of lag. From there, JVC says that up to two hours of compressed 4K video may be stored on a suitable high-capacity SDHC card. The GY-HMQ10 officially launches today, with availability expected in March at an MSRP of $4,995.
