With deluxe, leather and military options, the Gizmon iCA case is just the start of the system.

The case itself offers a hotshoe, shutter button and optical viewfinder. Available lenses screw into the case, or attach with a detachable clip.

You can choose from fish-eye, a CPL filter, wide-angle lens, tele lens, tunnel effector, macro lens and a mirage filter, which splits the image into three.

Cost: Cases from $55, lenses from $23
