**Rollei Extremium Round Filter ND1000/77, Like New, With Protective Cover**

ND filters with a comparatively high optical density are used in order to be able to achieve unusually long exposure times. The Rollei Extremium ND1000 filter extends the maximum available exposure time of your digital camera by ten aperture stops. It’s perfect for smoothing even rough water surfaces or to make moving subject components disappear. The Rollei Extremium Round ND1000 Filter has 10 stops, the absolutely homogeneous grey colouring of the extremely resistant Gorilla glass was provided with yet another layer. The Luminance Coating provides the high-quality filter glass with a protective layer, which doesn’t offer oil, water and other liquids any chance of being able to settle on the surface. You can remove even the most obstinate dirt without any problem. The particularly high light permeability and the unusual colour fidelity are guaranteed on a long-term basis by the Luminance Coating and reflections and mirror images are reliably prevented. The highest degree of colour neutrality is vital for the storage of unaltered, original image data.
