Everybody knows that something you can wear in a holster or in a quick draw style off your waist is cool. It just IS one of those things that is beyond debate. That said, I'm not so sure I want to wear my mildly expensive DLSR on my hip. I can see how useful it would be for quick draw shooting. But really, in that instance, I've got my camera around my neck already.
Notwithstanding the lack of a strap to help prevent the dreaded "Dropsies" where you go to grab your camera, almost get a full grip and pick it up only to have it slip out of your hands and towards the nearest rock hard surface it can find.
Also, this issue would be exacerbated by the use of a larger frame DSLR. It might be more doable with one of the new small frame mirrorless cameras though.
This solution seems to be asking to whack your camera into stuff when you forget its there. And that whack would be an expensive and painful one. Precision optics and getting slammed into hard objects are a bad mix.
While I think its a good idea, it also has some flaws but I suppose the type of person that would end up whacking their camera in a rig like this would probably be about as likely to smash it in a car door or otherwise destroy their camera.
