C Mike and Michael tested the new DJI Ronin-M Handheld Gimbal system with the Sony A7R II 4K Camera. The Ronin-M is made for smaller cameras like the Canon 5D, Sony A7s and A7R II, or the Panasonic GH4. The main advantage is that it weighs less, which is good news for your camera operator. In initial testing, the Sony A7R 2 camera looks great. It shoots internal 4K that can be viewed straight out of the camera.
