Sony FS700

Last updated by Yermy Weiss on May 28

The Sony FS-700 is the top NXCAM in Sony's line-up. It features the same adaptable E-Mount lens system as the FS-100 but features a much high resolution image sensor. Like all cameras in Sony's NXCAM line, the FS-700 records 1920 x 1080P in the AVCHD codec internally to SDHC/SDXC memory cards. The camera has 3G-SDI output, although without the 4K firmware upgrade it only outputs 8 bit 4:2:2. The FS-700 is also able to function as high-speed camera for short bursts. At Full HD it can record as much as 240 frames per second for up to 8 seconds. It can also shoot 480 fps and 960 fps at a reduced resolution.

While there are currently not many professional grade lenses available in the cameras native lens mount the shallow flange focal distance of the E-Mount makes it able to adapt to almost any other lens mount. The E-mount can easily be adapted to PL mount, Canon EF mount, Nikon F mount, Sony A mount, Leica M mount, Canon FD mount, as well as many others. Sony has also managed to squeeze in ND filters for adjusting exposure without affecting depth of field.

4K on the FS700

To record 4K with the FS700 a firmware upgrade must be installed by an authorized Sony technician at a Sony Professional Service facility. The Firmware update costs $400 by itself, but is free if purchased at the same time as the Sony HXR-IFR5 interface unit. Once the firmware upgrade is installed the FS700 is capable of outputting 12 Bit compressed 4096 x 2160 RAW over 3G-SDI. To record RAW you need both the Sony AXS-R5 recorder and the HXR-IFR5 interface unit. With this combo the AXS-R5 will record up to 60P continuous RAW in 4K, or up to 120P 4K in RAW for 4 second bursts. RAW files from the AXS-R5 recorder run about 960 Mb/s at 24P. That means about 7.2 GB a minute and 432 GB an hour.

 Another external recording option for the FS-700 is the Convergent Design 7Q. This recorder is unable to record in RAW but it can debayer the RAW in real time and record a 10 bit 4:2:2 4K compressed format that is promised to be very similar to ProRes or DNxHD. You do not need to purchase the HXR-IFR5 interface unit to use the Odessy 7Q with the FS-700, so if you don't need RAW this is a much more affordable and lightweight option for achieving 4K on the FS-700.
