Urth 127mm Circular Polarising (CPL) Lens Filter (Plus) | 20-Layer Nano-Coated, HD Optical Glass for Camera Lens polarisation

Pros and cons

Pros

The rotating circular polariser allows adjustment of the effect while composing.
The filter size is stated clearly as 127mm for lenses with a matching filter thread.
A slim rim is a useful design choice where vignetting is a concern, though the listing's claim is not an independent test.

Cons

A CPL reduces light reaching the sensor. Urth states a reduction of about 1.33-2 f-stops, which may require exposure compensation.

What to know before buying

Listing details to confirm

Check the lens's filter-thread diameter before ordering. Urth says it is usually printed beside the Ø symbol on the lens or cap. The supplied listing details are contradictory on the manufacturer's filter-material construction: the technical details say glass, while feature text also names a tough magnalium rim. Treat these as component-specific claims, not a settled claim that the whole filter is glass or metal. The listing also says the filter removes 99.9% of polarised light, but this is not independently verified.

Customer feedback describes the filter as well made and effective, with reported reductions in glare and improvements to saturation and contrast. Buyers also disagree about ease of use, and some report the lens cap falling off. For a 127mm lens, reported image benefits are relevant if glare control is the goal, while the reported cap issue matters when handling or transporting it. These are customer perceptions, not independent performance tests.

Positive themes

Customers report good build quality and effective functionality.
Customers report reduced glare and stronger saturation and contrast.

Negative themes

Some customers report that the lens cap falls off.

Mixed feedback

Feedback on ease of use is mixed.

Frequently asked questions

How do I check whether this filter fits my lens?

Check the filter-thread diameter, usually printed beside the Ø symbol on the lens or lens cap. It needs to match the stated 127mm size.

Can the polarisation effect be adjusted?

Yes. Urth describes the filter as rotating to adjust polarisation. Its effect depends on the angle of reflected light.

Does a CPL filter affect exposure?

The listing says it reduces light reaching the camera sensor by about 1.33-2 f-stops, so exposure may need adjustment.

What is included?

The explicit package contents list names one filter. Separate product-page feature text also claims a protective travel case, so confirm the selected listing if the case matters.
