The KODAK Multi-Purpose Camera Strap functions as a neck strap to hold various SLR cameras, or as a crossbody strap to carry compact cameras or smart phones. It adopts a Quick-Detach (QD) System which allows cameras to be released and interchange seamlessly, making it an incredible convenience. The O Ring is designed to change the strap from neck-use to crossbody-use, giving the strap more flexibility in usage.

Additional QD Snaplocks are also available so you can switch from camera to camera hassle-free!
