Sony PXW-X70 Camcorder (Black) Provides multiple choices depending on application required, including XAVC, AVCHD and DV file-based recording. When recording in XAVC, the PXW-X70 uses the MXF file format, efficiently compressing full HD resolution using the MPEG-4 AVC/H.264 HD CODEC. Image sampling is 4:2:2 10-bit with high-efficiency Long-GOP compression at 50mbps, 35mbps or 25mbps. The PXW-X70 is also 4K ready. The optional CBKZ-X70FX upgrade adds 4K to the PXW-X70 camcorder in 4K XAVC-Long format 4.2.0 8 Bit at 60mbps using the broadcast MXF wrapper. We are also looking to possibly support a higher bit-rate recording mode than 60mbps for 3840x2160 XAVC-L in the future. High sensitivity and fantastic resolution with 14.2 million effective pixels delivers striking detail and colours, even in low light conditions. The lens offers a 12x optical zoom, which can be increased to 24x with Clear Image Zoom while retaining full resolution thanks to Super Resolution Technology. Zoom performance can be doubled at any point with a digital extender by up to 48x.The PXW-X70 weighs less than 1.4kg, including the XLR handle unit, battery, lens hood and large eye-cup. It offers professional interfaces such as 3G-SDI and HDMI output connectors plus an XLR x2 handle unit with zoom lever. Other professional features include a manual lens ring that can intuitively control zoom and focus, ergonomic palm grip with large zoom lever, two SD memory card slots for backup, simultaneous and relay recording and a three-level switchable ND filter.
