Lensse is a company that makes very simple and affordable Video camera stabilizers that support iPhones all the way up to heavy DSLR bodies. These stabilizers balance your camera over a ball socket gimbal, attempting to prevent the transfer of shaky hands into the camera while walking, and also keeping your camera level with the horizon. You can see the complete line of stabilizers they offer (here).
Recently Lensse has just announced a new Stabilizer version called the UniqueX. It shares many of the same features at their other line of stabilizers, but the highlight of this new stabilizer is the adjustable Gimbal which can be relocated to the center of balance. Just another way of fine tuning the balance of your setup. Specs state it will support cameras up to 3 lbs and retails for about $100 bucks. Check it out via Amazon (Click Here).
