Filterfotograf® 100x150mm Center GND 1.2 (ND16) Rectangular Filter – Ultra HD Glass, Nano-Coating, Optimized Gradient by Riko Best

The Filterfotograf® Center GND 1.2 (ND16) is a high-precision 100x150mm rectangular filter with a central gradient, which was specially developed for scenes with a dominant light source in the center of the image - such as sunsets over a flat horizon line, reflective bodies of water or direct light sources on axis.

With a density of 1.2 (equivalent to ND16), the filter reduces light in the center of the image by 4 f-stops , while the upper and lower areas remain virtually unaffected. This ensures targeted exposure correction without unwanted darkening at the edges of the image.

Made from 2mm thick Ultra HD optical glass, this filter combines maximum image sharpness, color neutrality, and durability – designed for professionals and ambitious outdoor photographers.

Center GND – For difficult light in the center of the image

With its centrally positioned gradient, this Center GND filter is ideal for scenes where the strongest light is directly on or just above the horizon—such as sunsets over water or open landscapes. The ND gradient was developed by Riko Best himself based on years of practical experience with optical filters and specifically tuned to these lighting situations. The result is a balanced, photographer-friendly gradient that darkens the image in a targeted manner without unnecessarily affecting the upper or lower areas of the image.

Ultra HD glass – Maximum optical performance

The highly transparent Ultra HD glass delivers exceptional image quality, even with modern high-resolution camera systems. Absolute color neutrality and minimal light scattering ensure razor-sharp and realistic images.

AR+AF Nano-Coating – For clear vision in any situation

The filter is provided with an innovative AR+AF nano-coating :

• AR (Anti-Reflective) effectively reduces reflections and unwanted light glare – especially helpful in backlighting.
• AF (Anti-Fouling) protects the surface from oil, water, dust and fingerprints – for easy cleaning and a long service life.

Scratch-resistant & weather-resistant – developed for outdoor use

The hardened glass structure makes the filter particularly robust against scratches, dirt and weather influences – ideal for travel, mountain tours or long days in the field.
