The DJI Mavic Air is a wonderful drone capable of capturing 4K video and 12MP photos in the air. With the PolarPro Katana rig, you can use it to capture stabilized footage on the ground. It comes with a smartphone monitor, allowing you to frame each scene properly.
Katana allows you to take handheld shots in spaces not ideal for flying and no-fly zones. Costs under $50 at this time.
