I now own two of these protective coverings for my Nikon D80s. In addition to protecting the camera very effectively from bumps and scrapes they also make the camera easier to handle in many situations, maybe because I have quite large hands. All the buttons, sockets and controls remain fully accessible although it does help if you are reasonably familiar with the layout before the armo(u)r is fitted. A useful by-product of the protection is that the body of the camera can be maintained in near mint condition.
The only down side for me is the protection provided for the lens. This only works on smaller diameter lenses so is not particularly versatile.
In spite of the lens drawback I would recommend this product to anyone who enjoys being out and about with their D80.
