If you already have the GearBox itself, you will be able to upgrade to the 15mm Rod system with the GB-R Kit. For those who want both in one purchase, there will be a GB-2 GearBox Bundle available on the website.
Disclaimer: I help to design products for PhotographyandCinema.com. The article below is information about the new P&C GearBox. There are many other great DSLR style cages available within articles of this blog that you may also want to consider.
There are many High End, Super Heavy, Robust video cages available for the Professional market, but we found a lack of more affordable options for smaller style video cameras such as the Sony NEX-7 or Popular GH2. The P&C GearBox is designed to be simple, lightweight, modular, and of course - affordable.
The GearBox has a solid metal bottom and top bracket with several 1/4-20 mounting options for your accessories such as an LED video light, Portable Recorder, HDMI LCD Monitor, Microphone, Wireless Receivers, etc. To take up minimal space in a bag when packing up or traveling, the GearBox can easily be disassembled with a single Hex driver.
The GearBox will support a quick release plate underneath if you want to mount the rig onto a Tripod. Extension adapters are provided to support taller cameras, or if you want to add a quick release system into the cage unit allowing you easy removal of your camera body. The rubber coated side handles provide a non-slip comfortable grip and are spaced further apart to add stability for hand-held shooting styles. Interested in a Rail System? Soon to be released is the 15mm Rod adapter (sneak peek here).
