Pros & Cons

👍 Pros

  • Offers 6 stops of light reduction (ND 1.8), allowing for longer exposures or wider apertures in bright conditions
  • Constructed from 4 mm thick optical glass with precision cut, grinding, and polishing for optimal image quality
  • Features ultra low color shifting, ensuring accurate color reproduction in photos and videos
  • Comes with an anti-reflective coating to minimize glare and internal reflections for clearer images
  • The filter is water proof, scratch, and oil resistant, offering enhanced durability and easier cleaning
  • Optimized for shooting raw 6K digital images, catering to high-resolution professional workflows
  • The 4x4 inch size is a standard in cinema matte boxes, ensuring compatibility with professional setups

👎 Cons

  • The 4x4 inch size requires a matte box system for use, which is an additional investment and setup
  • A fixed ND 1.8 (6 stop) density might be limiting if varying light conditions require different levels of light reduction
  • The 4 mm thickness is standard for cinema filters but might not fit all filter holders or matte boxes without checking
  • While optimized for 6K, its specific impact on lower resolution footage is not detailed
  • Professional cinema filters typically come at a higher price point due to their specialized construction and performance
  • The square form factor makes it less convenient for hand-held use compared to circular screw-in filters
  • Specific light transmission efficiency percentage is not provided, though "ultra low color shifting" is noted
