Our entry-level Circular Polarizing Filter cuts reflected (polarized) light to increase contrast and boosts colour saturation and vibrancy.



Cut reflections, boost colour saturation and increase contrast by cutting out reflected polarized light.

Polarized light can wash out images with silvery reflected light and our Polarizing Filter cuts out 99.9% of reflected light from water, glass, and non-metallic surfaces, uncovering bolder colours.

Rotate our Polarizing Filter to improve colour saturation, contrast, and remove reflections. At full polarization, our CPL creates a 1.33 f-stop light reduction.

All our circular filters come with a protective travel tin case, a recycled cleaning cloth, and recycled plastic-free packaging.

How to Use

CPL Polarizing Filter 1Peak


Find your filter size

Search your lens and find the diameter symbol Ø followed by a number (e.g. Ø58 or Ø58mm). This can be found on the front or side of your lens – this magic number is your filter size. Note: Your lens focal length (e.g. 18-55mm) is not your filter size.

CPL Polarizing Filter 1Peak


Place flat and screw clockwise

Graciously behold lens in one hand and place flat on lens. Gently screw clockwise until just firm. Do not over-tighten – that which goes on must one day come off.

CPL Polarizing Filter 1Peak


Twist until you see it

Tenderly rotate the outer rim of your CPL Filter and watch as the level of polarization changes.

For best results

You’ll need to adjust your exposure setting for a 1.33 f-stop light reduction. For best results, use your CPL with landscapes, streetscapes, around water, windows, snow, clouds and ensure the sun is at 90 degrees to your lens filter.

Frequently Asked Questions

Which range of CPL should I buy?

Let the quality of your lens guide your choice. Or simply go for the best – our professional Plus+ range.

Urth has two different ranges of filters: Urth (our premium range) and Urth Plus+ (our professional range). Let the quality of your lens guide your decision. If you’ve invested in a professional-quality lens, we recommend you match its quality with our Plus+ range. Our Urth range is the perfect option for all other standards of lens.

How do I get the most out of my CPL?

Use the 90-degree rule, then back it off a bit.

To achieve the strongest polarization possible, the reflected light source needs to be at 90-degrees to your CPL. To check this, make an L-shape using your thumb and index finger. Point your thumb at the lens and wherever your index finger is pointed, that is the angle that will achieve maximum polarisation. Sometimes at full polarization, the effect can look unrealistic so we suggest you back it off a bit for a slightly softer polarization.

Can I use your CPL with wide-angle and telephoto lenses?

Yes, we recommend our Plus+ range for telephoto lenses.

Make sure you have the right size filter and you’re all set. All our filters are designed with a super slim rim to minimise any vignetting that can occur with wide-angle lenses. Because of the amount of glass in a telephoto lens, Ous Plus+ range will provide the best image quality.

What's the difference between circular and linear polarzing filters?

A circular polarizer blocks reflected light from any angle while a linear polarizer only blocks reflected light from one direction.

A CPL offers more versatility and works better with digital cameras. Both linear and circular polarizers look the same, and they both do the same thing – reduce reflections on non-metallic surfaces such as water, glass and wet surfaces, and they increase colour saturation too. A CPL filter is essentially a linear polariser with an extra glass element that allows you to adjust your lens filter to block polarised light from different directions.

Does a CPL affect my exposure?

Yes but only a little – 1.33 f-stops.

A CPL filter will reduce the amount of light reaching your sensor by about 2 f-stops.

Blue and green dream

Does a great job at poppin' those colours and is a nice small filer that looks pretty chill on these older lenses. I have had a couple CPL filters and these one is my favorite and finds a home on my lenses more then not. A killer product.
