SOLID
That’s the way I would describe this video platform for controlling your camera. Camtrol has spent some serious time designing their camera platforms and I take a peek the Prime 22 model here. The controls are strong. Easy to use. Very sturdy yet comfortable and at a price point 1/2 that of other camera mount control systems.
When paired with the Panasonic Lumix GH3 you have a very powerful video capture system. Check out the video for more on that… and if you have lots more time then money I give you a possible alternative to hold you over until you get to the professional gear.
