Ronin 4D Flex Extension Unit
The Ronin 4D Flex Extension Unit allows you to detach the lens/sensor/3-axis stabilization from the 4th axis and the rest of the body (taking the ‘head’ off the ‘neck’), and connect via a 6.6′ cable. Similar in concept to the Rialto for Sony Venice. Switching between the Flex unit and the integrated configuration on set is fast and does not require any tools.
The handgrips and onboard monitor can then be moved from the camera body to the ‘head’, making handheld operating even lighter, with the camera body mounted in a backpack or vest.
The Flex unit alternatively expands on the 4D’s ability to be a remote head using the wireless handgrips or wheels, allowing you to place the lens in tight spaces. Mounted to an extension boom pole, it can get jib arm camera moves or be be used as a kind of giant probe lens. Although you would lose the 4th axis stabilization, which is nice for moving vehicles, you could also use the Flex unit to reduce the amount of rigging you need to put outside a car, with the rest of the camera body staying inside. It can also be used to support much larger cinema lenses and zooms when locking off the stabilizer.
