I recently purchased an hvx200 and a Petro backpack to store it in. I like the idea of a backpack because it is soo much easier to lug things around. I was just wondering though, is the lens to my camera supposed to be facing up or down? It makes more sense down, as the viewfinder sticks out the back. But I heard some people say that with the ois it should be up??? Does anyone know if it actually matters?
