Pros & Cons

👍 Pros

  • Provides 6 stops of light reduction, allowing for longer exposures or wider apertures in bright conditions.
  • Features ultra low color shifting due to its anti-reflective coating, ensuring accurate color reproduction.
  • Constructed from 4mm thick optical glass with precision cutting, grinding, and polishing for high image quality.
  • Offers robust durability with water-proof, scratch-resistant, and oil-resistant properties.
  • Optimized specifically for shooting raw 6K digital images, catering to high-resolution video production.

👎 Cons

  • The 4x5.65 form factor requires a matte box system, which adds bulk and complexity compared to screw-on filters.
  • Being a 6-stop filter, it may be too strong for situations where only minor light reduction is needed.
  • Optical glass, while high quality, can be susceptible to breakage if mishandled, despite its durability features.
  • This specific filter is designed for professional video and cinema applications, potentially overkill for casual photography.
  • The anti-reflective coating helps, but some reflections might still occur in extremely challenging lighting scenarios.
