Urth 82mm Magnetic CPL Lens Filter Plus+

The Urth Magnetic CPL Lens Filter Plus+ is an 82mm circular polarising filter for compatible camera lenses. Its rotating polariser is intended to reduce reflections and adjust colour saturation, while magnetic attachment is designed for quick filter changes.

At a glance

The filter rotates so the polarisation can be adjusted for the scene.
Urth says the magnetic design speeds up fitting and removal and includes a magnetic adapter ring.
The listing claims 20-layer CoraNano coating and SCHOTT B270 optical glass.
The manufacturer says the slim rim is designed to avoid vignetting. This is a design claim, not a guaranteed result for every lens.

What to know before buying

Listing details to confirm

The listed model name says Magnetic CPL Polarizing Filter Plus+, while the product title calls it Plus. The page also describes German SCHOTT glass and a 20-layer coating, but the technical material field only specifies glass. Confirm the exact variant and material details in the selected listing. A CPL's effect depends on the angle of the light and filter rotation.

Who is it for?

A good fit for

Photographers using an 82mm lens thread who want to adjust reflections from water, glass or other non-metallic surfaces.
Users who value quick magnetic filter changes and adjustable polarisation.

Less suited to

Owners of lenses without an 82mm filter thread who do not have a compatible size adapter.
Buyers seeking a filter whose effect does not need manual adjustment.

Customer feedback is mixed on both optical quality and magnetic attachment. Some find the optics decent, while others are disappointed, and the magnet is described as convenient by one customer even though attachment feedback is mixed. These perceptions matter if consistent optical results or a secure, repeatable fit is a priority. The listing's coating and glass claims do not resolve those differing experiences.

Mixed feedback

Customers report mixed opinions about optical quality.
Feedback on the magnetic attachment is mixed, with one customer describing easy removal and refitting.

Frequently asked questions

Which lenses does this filter fit?

The listed compatibility is for cameras with an 82mm lens filter thread. Check the thread size marked on your lens or lens cap.

What does the rotating CPL do?

Rotation adjusts the polarisation, which the listing says can reduce reflections and increase colour saturation. The result depends on light direction and filter position.

Does it include a magnetic adapter ring?

The product feature text says magnetic filters include an adapter ring. Confirm that the selected listing includes it before ordering.

Can I stack it with other filters?

The product information says filters are double-threaded for stacking, but also advises using one at a time for best image quality because stacking can cause vignetting.
