Sony Pro Camcorder Delivers 4K Capabilities

PXW-Z100 uses XAVC workflow for production flexibility

PARK RIDGE, N.J.—Sony is expanding its line of professional 4K technologies with the new PXW-Z100 4K handheld XDCAM camcorder.

With a 1/2.3-inch Exmor R CMOS sensor, the camcorder can create 4K content at 50p or 60p. The PXW-Z100 camcorder is based on the same shooting ergonomics as a conventional handheld.

The PXW-Z100 camcorder, together with the fixed 4K-compatible high-performance G Lens, weighs less than 7lbs. The PXW-Z100 uses Sony’s XAVC recording. MPEG-4 AVC/H.264 compression is used for HD (1920×1080), QFHD (3840×2016) and 4K (4096×2160) content. Image sampling is 4:2:2 10-bit, with an intra-frame system that compresses each frame individually at a maximum bit rate of 500 Mbps or 600 Mbps during 4K 50fps or 60fps recording, and 223 Mbps during HD 50fps or 60fps recording.

Users can select QFHD (3840×2160) and HD (1920×1080) resolutions, which are compatible with most 4K TV’s.

The camcorder provides sensitivity due to its back-illuminated Exmor R CMOS sensor. With over 8.8 million effective pixels, the 1/2.3-inch sensor captures 4K images at 50p or 60p. The built-in G Lens offers shooting flexibility, including a wide angle of 30 mm in 4096×2160 mode or 31.5mm in 3840×2160 and 1920×1080 modes and 20x optical zoom (equivalent to 35mm).

The camcorder has two slots for XQD memory cards, which use the PCI Express interface and Sony’s camera processor to enable stable video recording at 500Mbps or 600Mbps.

The HDMI interface on the PXW-Z100 camcorder can output 4K as a 50fps/60fps signal. When the PXW-Z100 is connected to a Sony PVM-X300 4K professional monitor or a 4K-compatible Bravia TV, the recorded image can be displayed in 4K 50fps/60fps quality. A future firmware upgrade is planned to provide compatibility with HDMI 2.0 and enable 4K 50fps/60fps output to more devices. Other features include a 3G HD-SDI interface that supports output to an SDI of up to HD 60p. It also supports HD output during 4K recording.

Its paint function enables multiple image parameters to be adjusted. Parameter settings can be recorded as a camera profile onto a memory card, and the recorded camera profile can then be used to set the same parameters for a multi-camera setup.

Users can remotely control focus, zoom, aperture settings and “record start/stop” using the browser function of a smartphone or tablet.

The PXW-Z100 4K camcorder is slated to be available by the end of 2013.
