This is a completely new type of camera strap that you can adjust and fix to the exact length you want with one finger. It is named "Easy Slider" (registered as a utility model). Put your finger through the D shaped hook, and simply pull up to shorten the strap and pull down to extend the strap. It is a superior camera strap that if you release your finger from the hook, the strap will stay fixed at the adjusted length. The ring type is newly introduced this time in addition to the tape type which is already very popular since its introduction.
