Okay, I admit that does not have to be very comfortable to carry in your pocket but that this case literally 4/4S iPhone Apple transforms your phone into a camera with clear echoes of the classic Leica rangefinder . The ICA Gizmon includes optical viewfinder, tripod mount, strap grips adapters and support for macro and fisheye.
The case is made with 23 parts of polycarbonate and is available at a price of $ 65 in three colors : white, brown and black, plus a fourth model Military Edition completely black for $ 70. The manufacturer seems determined to make all kinds of accessories for the system include ICA or external Flash, a neck strap with helmet, a leather case and an extensive collection of lenses.
I recommend that you perceive a walk on the Gizmon website for more images of the cover and each of its accessories. I am resisting with all my might the urge to order one so I hope you have better luck than me.
