I use these covers on all my camera bodies. They protect against scratches and dents should you have an mishap.

You may temember back in the day how serious cameras always had a hard leather case for protection. We moved to just carry the camera on a strap, but using a camera in general exposes it to little impacts when going through doors and the like. While I am not convinced it would give full drop protection, it does help with the minor bumps. This is my second case of this type, as I have one on an underwater and sports camera. I would like to see one improvement: have a white dot at about 2 oclock on the lens ring for lining up a lens to be mounted, as on the body itself.
