Sony is continuing the evolution of its XDCAM line of "tapeless" products. The Japanese company launches today at the NAB video expo its latest "prosumer" targeted flash-based camcorder. The XDCAM EX is a new budget pro video camera, one of Sony's first high-end cameras with movement-free storage.

The camera records raw MPEG-2 video at up to 50 Mbps 4:2:2 to flash memory by using the faster ExpressCard 34 format found in modern Windows compatible Mac and laptops. Sony&SanDisk SxS high-speed cards (compatible with ExpressCard slots) will allow you to store up to two hours of HD video on a 16 GB card (8GB will also be an option) that can then be transferred to a portable. This can be really useful for you if you need quick access and good transfer speeds. Video is recordable at a full 60 Hz or a film-grade 24 Hz.

In other news from the NAB video fest, Sony is also unveiling a new optical-disc based XDCAM products, including the PDW camcorder, PDW-F75 deck, and the PDW-U1 external drive. These are also models are part of Sony XDCAM product line.

Sony hasn't talked about any exact date for the release of the three-sensor camera or its curious SxS storage format, but they said it will probably be out in Fall 2007. There's also no word about the price. The company revealed that it will also launch the Blu-Ray based PDW-F355 recorder with 50 GB of storage along with an external deck and optical recorder at about the same date.
