Urth 62mm Circular Polarising (CPL) Lens Filter

A CPL filter reduces glare and reflections from non-metallic surfaces like water and glass, and it enhances color saturation and contrast, making skies bluer and foliage greener.

Check the front of your lens. You will typically see a diameter symbol (Ø) followed by a number, like 'Ø62mm'. This indicates the filter size needed.

CPL filters can reduce the amount of light entering the lens by 1-2 stops, which might require adjusting your exposure settings (e.g., slower shutter speed). Modern autofocus systems are generally unaffected, but in very low light, autofocus performance might be marginally impacted due to reduced light.

While looking through your camera's viewfinder or at the live view screen, rotate the outer ring of the filter. The effect will change as you rotate it, allowing you to find the optimal setting for reducing reflections or enhancing colors.

Yes, you can stack this CPL filter with other filters like ND or UV filters, but be mindful that stacking can increase the risk of vignetting on wider lenses and potentially reduce image quality.

The 8-layer nano-coating improves light transmittance, reduces lens flare and ghosting, and makes the filter easier to clean by repelling dust and water.

Urth partners with environmental organizations, and a portion of the proceeds from each filter purchase is allocated to planting trees in areas affected by deforestation.

This can happen with wide-angle lenses. Try using a slimmer profile filter if available, or ensure you are not using the filter with a lens that is too wide for its mount.

Ensure you are using the correct filter size (62mm) and that the lens threads are clean. Try screwing it on gently and straight.

Ensure the filter is rotated correctly to achieve the desired effect. The CPL's effectiveness varies with the angle of the light source (sun) relative to the camera. Also, check that the filter is properly seated.
