Especially since I have been working for years with Nikon and there supplied Nikon original plastic screen protector can very quickly ruin the underlying display. Come namely sand or similar zwichen display and the loosely plugged Protection and the camera worn on a belt, it is not long until the display is scratched beyond repair.
This can fortunately be bypassed with the Echtgals screen protection. In the 2012 version additionally provided for the protection for the main display with a tiny unobtrusive protection framework, the more harmoniously integrated into the camera the whole design. Unlike the versions without the protection frame, you can not see so the thin edge of the glass, but a very narrow circumferential rubber edge.
The - not really necessary - protection for the Topdisplay is carried out without the protective rubber.
Whether the matter, the impact resistance is now actually quite hilly, sometimes an open question, visually definitely an asset.
Supplied in plastic box, similar to filters.
