OP/TECH USA straps have always benefited from the ability to mix and match components by using our large selection of system connectors In order to build a completely customized strap. The system connectors - mini QD Step-Up combines our small Mini QD loop with our standard 3/4” Quick disconnect. For small cameras with tight connection points, this connector lets the user “step up” to a bigger OP/TECH USA strap if desired (IE. Utility sling, super Classic strap-uni loop, bino/Cam harness, double sling, etc. ) This is ideal for many of the mirrorless m 4/3 cameras where you may want to use an existing OP/TECH USA strap or the double sling with the mirrorless camera on one side and a larger SLR on the other side. The system connectors - mini QD Step-Up can be used any place where one of our system connectors - Uni-Loop connectors is already being used. The thinner cord loop connection of the system connectors - mini QD Step-Up makes it possible to attach to tight connection points on a camera and gives you more versatility in your choice of camera. This allows for a quick change from a full-size D-SLR camera to a smaller camera in just a few seconds!
