anyone heard of this new add-on for Hero 3's called the RibCage?
essentially lets you use any camera lens on your gopro, and its less than $300 on top of the gopro itself.
I know exactly shit all about photography but from what I've seen it seems pretty solid.
Anyone with photography knowledge have any insight?
