By technical editor Matt Allard:
Fotodiox had some prototype camera cage solutions on display on their booth at NAB. A range of solutions was available for cameras such as the Blackmagic BMPCC, Panasonic GH4, Samsung NX1 and GoPro. All the cages are minimalist in design and allow for easy access to the controls, with lots of mounting points for adding accessories.
The Blackmagic BMPCC cage will be available very shortly for $325 US. The GH4 and NX1 pricing and availability will be announced soon.
