After hinting that we might see something soon, Sony have officially released their 4K recording path for the FS700.
OPTION 1 – Sony
With an optional firmware upgrade the NEX-FS700E will output 4K bitstream data over 3G HD-SDI. The HXR-IFR5 interface unit has a 3G HD-SDI input and will produce the 4K RAW data to record onto the Access Memory Card in the AXS-R5 Recorder.
OPTION2 – Convergent Design Odyssey 7Q due to ship in Mid July
Will record 2k raw output 240fps continuously for 45 minutes using 2 x 960GB
And 4K up to 30fps.
