What to know before buying

Listing details to confirm

The listing is inconsistent about coating-layer count: one feature states 8 layers, while the product description claims 20 layers for the Plus range. Its 99.9% claim refers to polarized light in one feature and reflected light in another, so treat these as listing claims rather than settled measurements. The listed model identifier also differs from the manufacturer part number shown in the details. Verify the selected version and identification before buying.

Who is it for?

A good fit for

Photographers with a lens that has a 49mm filter thread who want adjustable polarisation.
Buyers aiming to reduce reflections from water or glass and adjust colour saturation.

Frequently asked questions

Will this filter fit my lens?

The listing gives a 49mm thread size. Check the filter-thread marking on your lens, as the camera model alone does not establish fit.

What effect does the filter provide?

It is a circular polariser that rotates to adjust polarisation, with the stated aim of reducing reflections and enhancing colour saturation.

How many coating layers does it have?

The listing gives conflicting figures: a feature states 8 layers, while the product description states 20 for the Plus range. Confirm the version before relying on either figure.
