The UltraFit attachment mechanism has a greased bearing which allows your camera to freely rotate without becoming unscrewed from the strap, but it is important to periodically check the tightness of the screw. Secure your sling strap to your camera by tightening the thumbscrew completely. For an even more secure grip, use a quarter to tighten down the screw. Just like JOBY revolutionized camera tripods, JOBY set out to transform camera straps. To replace the boring strap that came with your camera, we've created a dynamic and innovative camera strap that makes your photography fast, comfortable and more fun. Start to finish, the UltraFit Sling Strap for Men is pure JOBY design and innovation. Scroll to learn more.
