At NAB 2017 LanParte came out kicking and screaming with a new line of cage and rigging products called the Dragon Kit.
Thanks to Bart Johnson Productions for the update.
Called the Dragon Kit, this cage system is based around caging your lens adapter and leaving your camera and lens free to be easily removed and swapped. While LanParte does plan on providing their own adapters, the plan is for the system to be able to house all of the most popular lens adapters, including Metabones Speedboosters. This eliminates the need to purchase a new camera cage whenever a new camera comes out with a different body design!
