Ordered believer losing one of my 50, this cap is an exact copy of the original. There was even the Nikon logo on any time after finding the one provided with the objective it appears that the spring whines a little and that the moving parts rub a little of what does not affect the function so I put him anyway 3 stars because it's not a bad product. It's just a product less pleasant to use but for the cost it was worth the money compared to the original on the Nikon store.
