Premium round filter gray filter ND8

ND filters / neutral density filters such as this 49mm ND filter with a strength of ND8 (3 stops / 0.9) are used by nature and landscape photographers, for example, in order to be able to extend the exposure time - helpful to remove people and cars in front of buildings when they are architecture -Want to shoot in busy city centers. As a moderate neutral gray filter, the Rollei Premium round filter ND8 extends the possible exposure time by three f-stops and provides a good basis for different photo ideas. ND filters achieve this through the neutral gray tint of the filter glass , which reduces the amount of light falling on the camera sensor falls. Depending on the ND strength, you can take long exposure times in daylight or with an open aperture in backlight. This is also useful in landscape photography, for example, if you want to photograph flowing water with a velvety soft surface and flowing movement. Due to the color of the filter glass, the premium ND filters are also called gray filters .

Gorilla®* glass protects the 49mm ND8 Premium filter from rough handling

The Rollei Premium 49mm ND8 filter consists of the particularly resistant Gorilla® glass from the American supplier Corning Inc. The glass blanks are exposed to an extremely hot alkaline solution, which ensures ion exchange at the molecular level. The surface tension of the glasses is increased and made insensitive to mechanical influences, weather influences or pressure. Even if the glass surface is damaged, there is no risk of further material chipping, the scratch does not spread. You can also protect the compact and round camera filters by conveniently and safely transporting them in one of our camera backpacks .

Multiple remuneration & quality control with high standards

After another special treatment of the filter glass, the Luminance Coating developed in-house, the filter surface has a kind of "defense shield" against oil, water and dirt and gains enormous resistance to mechanical stress thanks to the final anti-scratch layer. The high light transmission and an outstanding color neutrality is maintained by the Luminance Coating, and distortions and reflections are also effectively prevented. The best prerequisites for securing the optical characteristics of the original motif in its purest form. In order to be able to guarantee these unique optical and material properties, Rollei has introduced a particularly strict quality management system. Rollei Premium round filters ND8 have been meticulously checked several times, the Rollei filter experts have already precisely defined each subsequent production step during development. The Premium ND8 filter is available in the nine most common lens diameters from 49 to 82 mm . Incidentally, gray filters can be easily combined with polarizing filters and gray graduated filters .
