This strap came with something I purchased, but I've forgotten what it was for. You can attach whatever you like to it. It's made of fairly sturdy material, so it should be able to hold the weight of a camera. I believe it's made of nylon. The shortest length is 66cm, and the longest is 127cm, but these are approximate lengths. I don't remember using it, but please consider purchasing only if you understand that it is a used item. I plan to ship it via regular mail, but I may change the shipping method to Yu-Yu Mercari Delivery.
