The HDx1.4 adapts B4 mount video lenses to cover a single sensor Super16, magnifying the image slightly and correcting for the lack of a prism.
This allows a coverage of 1080p on the following cameras with a light loss of just one stop: Phantom Flex 4K, 2K, Sony F5 or F55, Blackmagic Pocket Cinema camera and others.
Like the HDx35 Mark III and HDx2 Mark II the HDx1.4 uses the IB/E Universal Mount System (UMS), so the mount can be switched between ARRI PL, Sony E, Canon EF, Micro 4/3 and Nikon F.
