The unexpected genius of the gliding camera strap is that it allows your dSLR to glide along the length of the strap. So the camera hangs comfortable by your side when it's idle, but can be drawn at a moment's notice when you need it.
Gliding camera straps are sold online, starting at about $60. Test out the concept by making your own for less than $10. Pictured here are the items you'll need to make it.
First, grab the camera strap included with your camera. Tie the two ends to form small loops, as if you were attaching the strap to either side of the camera body. Make sure the loops are tight and will not come undone.
Insert the two ends of the camera strap into the quick release (or carabiner). Secure it. Your camera strap should now form a complete circle.
Screw the eye bolt into the camera as far as it will go. Then, screw the nut over the bolt until it reaches the camera body. Tighten it with an adjustable wrench or a pair of pliers. A little twist is enough to ensure that the screw won't come loose while the camera is dangling by your side.
Secure the clasp around the eye bolt. Then, insert the key ring into the opposite side of the clasp. Finally, secure the key ring around camera strap.
To properly wear the strap, place it across your body and adjust it so that the thick part of the strap is in front of you. Your camera is now ready to glide.
Each time you wear your gliding camera strap, check all the connections.
Your gliding camera strap is complete! If you wish, you can spray paint the silver components to match the color of your camera.
