FS5 now shipping. Review by Newsshooter.

The new FS5 4K E-mount camera is now in Stock and shipping at Adorama (Click here) and BHphoto (Click here).

And Newsshooter reviewed the FS5 with Kai from Digitalrev:

As a B-camera on larger productions the FS5 should work well in places where you might previously have used a DSLR, GH4 or Sony a7S. Obvious uses include on brushless gimbals and in-car rigs, although you will probably want to record externally.

Newsshooter also tested the camera at anti-war protests:
