Sometimes you want to use you're strap.
Some times you don't.
Therefore I created the DSLR Strap clamp!
Please note I have used the strap of the Eos100d others straps may be to wide a narrow.

Please DONATE if you like my designes!!

Best is to use a tripod screw for attaching it to you're camera.
Search on ebay for: "1/4" D-Ring Screw Thread Bolt For Camera Tripod"
Also some anti-slip rubber would be good for between the camera and clamp
