There's no quick easy way to switch straps on a DSLR. So I went to Lowes and bought this inexpensive hardware.
I used the smallest key rings (3/8") from this multi-pak and installed them onto the metal strap loops on the camera.Then I put mini carabiner clips on the end of the stock Nikon strap and the new handstrap.
So now, when I'm shooting around the house I ditch the stock strap in a matter of seconds. And anytime I want to swap out straps it's a snap!
