The JJC NS-J2 strap is made of polyester and metal material, lightweight and comfortable. The strap is worn diagonally across the body from the shoulder to the hip. With its comfortable shoulder pad design, the weight of the camera is distributed evenly, helping to relieve fatigue during extended shooting sessions. The 1/4'' metal screw easily screws into your camera's tripod socket. The strap and high-quality metal screw base are connected with a reinforced swivel hook to ensure the security of your camera. The length of the strap can be easily adjusted to fit your comfort and shooting style through the locking adjuster on the strap. Additionally, the NS-J2 strap is designed with a safety belt that connects to the camera's strap hole to protect your camera in case the metal screw loosens accidentally. There is also a zippered pocket on the strap for storing camera accessories, such as memory cards.
