The Rollei F: X Pro Hard GND 8 3 stops / 0.9 is a gray graduated filter. The abbreviation GND stands for graduated neutral density, which means a gray filter with a transition from tint to transparency. With graduated filters, the coating runs out to one side. The word hard means that the filter has a very hard transition from the dark to the transparent area.hat.
The hard GND can be used for these motifs:
- Recordings by the sea
- Sunrise or sunset with a clear horizon line
- Subjects with a clear horizon line and a large imbalance in brightness
Unlike normal ND filters, GNDs are used for motifs in which the brightness ratios have a certain gradient and therefore require a different exposure for an evenly exposed image. A classic location of a Hard GND is, for example, a sunset on the beach, where the foreground does not have to be darkened, but the background is still very bright due to the sun and therefore has to be darkened. The Hard GND compensates for such scenarios.s.
Our Hard GND 8 is available in a size of 100 millimeters. It has a density of 0.9 and 3 stops. A stop means that the amount of light falling on the sensor is reduced by one f-stop at a time.
Exemplary color fidelity with extremely fine coating
We have provided our GNDs with our Luminance Coating, which ensures that the filters are free of reflections at 99.5 percent. This guarantees you razor-sharp images even with high-end cameras with 150 MP. The color fidelity is exemplary, which means for you that you can capture your motifs exactly as the human eye sees them.ht.
Our filters are made from Gorilla Glass. This makes it extremely resistant and at the same time offers high color neutrality and light permeability. With our anti-scratch layer, the glass gets its final hardness against mechanical influences. In this way, sludge and dirt from grease or water can be removed quickly and easily..
But our filters are not only equipped against mechanical influences. We have tested and proven this in both heat and extreme cold. Our filters can only comply with all of this because our quality process works according to the AQL principle of Acceptance Quality Limit, which means acceptable quality limit in German. This means that if a certain number of random samples of a production lot does not meet the quality criteria, the total scope of the lot will not be accepted.ird.
This process is repeated after delivery so that you can be sure that your valuable Rollei filters are always of the highest quality.
*Note: Gorilla Glass is a protected word mark of the Corning company and is used by us for our filters.g.
