Pros & Cons

👍 Pros

  • Offers a 4 Stop Infrared Graduated Neutral Density filter, allowing for precise control over exposure in challenging lighting.
  • Constructed from 4mm thick optical glass, ensuring high optical quality and durability.
  • Features precision cut, grinding, and polishing, which contributes to excellent image sharpness and clarity.
  • Designed with ultra-low color shifting and an anti-reflective coating, maintaining accurate colors and minimizing unwanted reflections.
  • Provides water proof, scratch, and oil resistant properties, enhancing its longevity and ease of cleaning in field conditions.

👎 Cons

  • As a 4x4 inch filter, it may require a specialized filter holder system, which is typically sold separately.
  • The "4 Stop" density might be too strong or too weak for some specific lighting scenarios, requiring additional filters.
  • The term "Infrared Graduated Neutral Density" implies it also filters IR light, which might not be necessary for all photographers.
  • The 4mm thickness, while robust, could potentially lead to vignetting issues on very wide-angle lenses when stacked with other filters.
  • Being a specialized filter, it represents a significant investment compared to standard neutral density filters.

Frequently Asked Questions

This means the filter reduces light by 4 stops (equivalent to a 1.2 density) and also blocks infrared light, which helps prevent color shifts in certain long-exposure situations.
This filter measures 4x4 inches and has a thickness of 4mm, made from optical glass.
No, it is designed with ultra-low color shifting and an anti-reflective coating to ensure accurate colors and minimize reflections.
The filter is constructed from 4mm thick optical glass and features water proof, scratch, and oil resistant properties for enhanced durability in various conditions.
As a 4x4 inch square filter, it requires a compatible filter holder system designed for this size, which is typically purchased separately and then mounted to a lens.
This NiSi filter is optimized for shooting raw 6K digital images, indicating its capability to maintain high image quality with high-resolution sensors.
