It's a "rangefinder" case for my iPhone 4s complete with a working shutter button, tripod mount (!) and 3 lenses (wide angle/macro, telephoto, and fisheye). It's got two little holes for a slim strap (which I plan to add).
Taking it off and putting it on is not exactly "quick" (I feel like the guy in the movies after he gets off the plane and heads to a restroom stall with his briefcase so he can assemble in private the sniper rifle that looks like it's built of Lego blocks) but I'm sure I'll get faster. It comes with a soft little bag, and my plan is to keep the "case/lenses/strap" in the bag, and put it on my iPhone when I head out for a walk. Dorky? Definitely. But awesome at the same time.
Check it out here at the Photojojo store. They have tons of cool camera stuff besides this, too!
