Sony is expanding its XDCAM-EX line-up with the launch of a 3 CCD (1/2 inch) semi shoulder-mount HD camcorder with interchangeable lens.

The PMW-EX3 is the second camcorder from Sony to use the SxS media format, a flash memory card similar to Panasonic's P2 card.

It is larger than the first EX solid state camera, the PMW-EX1, and has a fold-out shoulder-mount.

The new camcorder can switch between 1080i and 720p recording and has both genlock and timecode connections for multi-camera shoots.

Many of the PMW-EX3's features, including gain, iris, white balance and gamma can be altered via remote control. Unlike the EX1, the lens on the EX3 is removable allowing shooters to use a different type of lens if required.

“The camera has been designed to appeal to a range of markets,” said Sony UK marketing manager Carl Pring at NAB. “The genlock suits those working in studios, the shoulder mount suits videographers and the interchangeable lens suits natural history. There is huge interest from visitors.”

The PMW-EX3 is expected to launch in June this year and will cost around£6,500.

Sony also announced the PMW-EX30, a player/recorder which features an HD-SDI in/out, and an external 60GB hard disk storage unit - the PHU-60K.

The latter is a 60GB external storage unit with an USB 2.0 interface that allows users to achieve approximate recording times of 200 minutes in 35Mbps HQ (high-quality) mode and 260 minutes in 25Mbps SP (standard play) mode.
