39mm circular polariser for photographers

The Urth 39mm Circular Polarizing Lens Filter Plus+ fits lenses with a 39mm thread and is built for photographers who want stronger colour saturation and fewer reflections from water, glass or other non-metallic surfaces. It uses German SCHOTT B270 optical glass with 20 layers of nano-coating to resist water, oil and scratches while maintaining high light transmission. The ultra-slim magnalium rim reduces vignetting risk on wide-angle lenses.

Check thread size and filter stack

Verify that your lens barrel is marked 39mm before ordering; the filter will not fit other diameters without a step-up ring. The double-threaded rim allows you to stack another 39mm filter or snap on a lens cap, but each extra layer increases the chance of corner shading on very wide focal lengths. Ensure the front element rotates freely so you can adjust the polarisation effect while composing.

Upgrades from basic or uncoated polarisers

This filter replaces a standard circular polariser that lacks multi-layer nano-coating or uses lower-grade glass, giving you 99.9% reflected-light reduction, smoother rotation and easier cleaning. The jump is worth it when you shoot landscapes, architecture or portraits where glare control and colour depth matter most. It is not for shooters who need a larger thread size or a variable ND function.

Questions about this item

Does the Urth Plus+ filter come with a case or do I need to buy one separately?

The filter ships with a protective case and a microfibre cleaning cloth included in the box.

I only see a 39mm version listed; how do I know this is the right size for my lens?

Check the front of your lens barrel for the diameter symbol followed by 39mm; this filter fits threads of that exact size.

What does the 99.9% reflected light reduction mean when I am actually shooting outdoors?

It removes almost all glare from water, glass and foliage, letting you capture deeper blue skies and richer foliage colours.
