Do I need a camera case and why? Without a case, I would just carry it around my neck; I don't need to carry it for a long distance, usually just from my car to a building. Would I just need a case for transport so the camera doesn't roll around in the car? If I should get a case, which one should I get? The camera is the Fujifilm HS30EXR with dimensions 130.6(W) x 96.6(H) x 126.0(D) mm
