I've got a Nikon with the default camera strap and I bought a BlackRapid shoulder strap. I had in mind being able to use either of them, but not both at the same time. The problem is that I find it takes some time to change between straps, usually when I remove or reattach the neck strap.
Is there any alternative that would let me detach and reattach the neck strap without having to remove it entirely? More or less like BlackRapid's hook that you can attach or detach from the bottom of the camera.
In case they're different depending on the camera, I have a Nikon D90.
