Well, no doubt that Nokia is a very good protection in this "cloak". When photographing I have but for "trigger" set me on the screen, I would like to by vertical pressure by the cover, provoke instability in trigger. The biggest benefit for me is that one for video recording, the lens unit very securely to any window, whether the train compartment or aircraft cabin, can push so that light from the side Keep away. Because where the lens cover encloses the cover, a fairly strong rubber lip is outwards standing that enables Nokia to push against the plate and shaker in the cabin or the Train compartment cushion effect.
