Sony to Release α7R II Firmware Adding Uncompressed 14-Bit RAW on October 19th
NEW YORK, Oct. 15, 2015 – Sony Electronics, a worldwide leader in digital imaging and the world’s largest image sensor manufacturer, will release a firmware update on October 19th that adds uncompressed 14-Bit RAW image capture to the acclaimed α7R II full frame interchangeable lens camera.
The new firmware, version 2.0, will be available for download through Sony’s e-support site www.esupport.sony.com on the product page for model “ILCE-7RM2”. In addition to uncompressed RAW capture, which will become a selectable feature (uncompressed/compressed RAW) within the menu system for updated cameras, the firmware also adds the ability for the α7R II to output video via HDMI during use of the Remote Camera Control software, that enables remote capture from a connected computer.
The α7S II and α7R II are compatible with Sony’s growing lineup of α -mount lenses, which now totals 64 different models including 13 native ‘FE’ full frame lenses. In 2016, Sony aims to build the native FE lens lineup to over 20 different models.
