The Zhiyun-Tech WEEBILL-S Handheld Gimbal Stabilizer incorporates the underslung mode design of its predecessor, the WEEBILL LAB, and also has a more compact form as well as other new features. The sling mode design consists of a handle on the rear that allows for easy switching to underslung mode as well as better handling in all other modes. Other improvements include upgraded motors and stabilization algorithms. The Zhiyun-Tech WEEBILL-S Handheld Gimbal Stabilizer features 300% more motor torque and 50% more responsiveness. This allows you to better balance camera/lens combos such as the Canon 5D Mark IV with a 24-70mm zoom lens.
