Pros & Cons

👍 Pros

  • Features a hard grey gradient to the filter center and a soft grey gradient to the top edge, ideal for landscapes with bright horizons
  • Offers a 4-stop light reduction (RGND16, 1.2), effectively balancing exposures in high-contrast scenes
  • Constructed from 2mm thick German Schott glass, ensuring exceptional optical clarity and durability
  • Equipped with ultra-slim multiple Nano-coating on both sides, which minimizes reflections and maintains image quality
  • Includes an additional protective film on both sides, making the filter water-, grease-, and dust-repellent for easy maintenance

👎 Cons

  • The reverse graduated design is highly specialized, primarily suited for specific landscape scenarios with a bright horizon, limiting its general applicability
  • Requires a compatible 100x150mm square filter holder system, which is an additional investment and can add bulk to a camera setup
  • While durable, being a glass filter necessitates careful handling to prevent scratches or breakage
  • The 4-stop reduction may not be sufficient for extremely bright conditions or for achieving very long exposures
  • The hard and soft gradient transitions are fixed, which might not perfectly match every scene's horizon line
