What if you wanted to use a neck strap for say landscape work and a wrist strap for street and urban style pics. Its too much of a faff to unbuckle one and put on the other, so what is the solution?
It is these Op Tech System Connectors:
I bought these 1.5mm connectors and I use them when I am not using the strap that came with the camera, with this Maveek paracord wrist strap.
