Hard GND – Precise gradient for clear horizons
With its hard transition edge, this GND filter is ideal for subjects with a clear horizon line—such as at the seaside, in the desert, or in the mountains. The ND gradient was developed and continuously optimized by Riko Best based on years of practical experience with optical filters. The result is a particularly precise, photographer-friendly gradient that reliably impresses in real-world lighting situations.

Ultra HD glass – for razor-sharp results
The Ultra High Definition glass used guarantees maximum light transmission and excellent optical quality—ideal for modern high-resolution camera systems. Color casts and loss of sharpness are a thing of the past.

State-of-the-art AR+AF nano-coating
The filter is equipped with a sophisticated multi-coating that combines the following properties:

• AR (Anti-Reflective) minimizes reflections and flare for clear, high-contrast images – especially in backlit shots .
• AF (Anti-Fouling) dirt and water repellent – ​​oil, dust or fingerprints can be removed effortlessly.

Robust and durable – built for outdoors
The specially hardened glass surface makes the filter extremely scratch-resistant and durable—ideal for daily outdoor use. The nano-coating provides additional protection against environmental influences and makes cleaning much easier.
