Hot on the heels of the FS100, this compact, highly modular camera uses a very similar-sized Super 35 CMOS sensor as the FS100. But as a marked improvement over that earlier model's sensor, the FS700 features a native 4K resolution sensor.
Unlike smaller, broadcast-style sensors or the larger "full-frame" sensors of some DSLRs, the NEX-FS700's imaging area matches that of standard Hollywood film cameras, providing complete compatibility with cine-style film lenses (sold separately). The sensor's large size offers a variety of other advantages, including increased control over depth of field, higher sensitivity in low light, lower image noise, and an exceptional dynamic range.
Able to shoot full 1080p video in a range of frame rates up to 60p, the FS700 provides the option of recording AVCHD footage onto SD card/MemoryStick or via the FMU (flash memory unit) port, or it can output 4:2:2 video (with embedded timecode) via HDMI 1.4 or 3G/HD-SDI to an external recording unit. Simultaneous recording to both is also possible when instant backup is called for. There's no stinting on audio, either, as the camera includes not only a shotgun microphone with mount/carrying handle, but dual XLR inputs for recording uncompressed, professional-level sound from an external source.
One unique feature for a camcorder of this class is the FS700's ability to record bursts of super-slow motion video at rates up to a whopping 960 fps. (These bursts range from 8 to 16 seconds, depending of the frame rate). Full-resolution recording is possible at up to 240 fps; at 480 and 960 fps, resolution is reduced.
The 3G/HD-SDI port will get expanded capability when a future firmware upgrade is available (not included). This will allow 4K output via the BNC as a data stream, which can be recorded to an optional Sony 4K recorder.
