Pros & Cons

👍 Pros

  • This Sigma circular polarizer effectively reduces unwanted reflections from non-metallic surfaces like water or glass.
  • The filter is super multicoated, offering enhanced light transmission and reduced internal reflections compared to single-coated filters.

👎 Cons

  • Despite being multicoated, some light loss is inherent to polarizers, potentially requiring longer exposures.
  • Specific details about the frame thickness are not provided, which might be a concern for vignetting on certain wide-angle lenses.
  • The 46mm size is specific, meaning it will not fit lenses with other filter diameters without an adapter.
