What to know before buying

Listing details to confirm

The listing describes this standard filter as having eight nano-coating layers, but its separate description refers to a Plus+ filter with 20 layers. Its reflection claims also vary between 99.9% of polarized light and 99.9% of reflected light. Confirm which specification applies to the selected filter. The listed screen size is inconsistent with a lens filter, so it should not be treated as a useful filter dimension. The lifetime-quality copy says it is backed for life, but warranty terms are not provided.

Who is it for?

A good fit for

Photographers with a 77mm lens thread who want to adjust polarization to manage reflections.
People seeking a slim-rim CPL filter for landscape, water or glass photography.

Less suited to

Aggregate ratings are mostly in the higher star categories, but a smaller one-star share means experiences are not uniformly positive.
