I never thought I'd call a camera strap innovative, but LumaLoop takes the idea of a camera sling and carries it a few steps further, into a totally customisable setup that makes your camera super accessible.
It's not cheap at $US60, but if you're serious photographer in the field it might be well worth it. I can't wait to check it out, myself. Update: Yes, it is similar in some respects to Black Rapid's R-Strap. [LumaLoop]
