The Urth 86mm Circular Polarizing (CPL) filter with Rotating Adapter is designed for photographers using 100mm Square Filter Holders, particularly those focusing on landscape or architectural subjects. Its primary benefit is reducing distracting reflections and glare from surfaces like water and glass, while simultaneously enhancing image contrast and color saturation. A potential consideration is its specific compatibility with 100mm square filter systems, requiring an appropriate holder. Key features include precise polarization adjustment, superior optical glass for sharpness, and a commitment to environmental sustainability through tree planting initiatives.

A CPL filter is used to reduce reflections from non-metallic surfaces like water and glass, and to increase color saturation and contrast, particularly in skies and foliage.
The rotating adapter allows you to manually turn the CPL filter element within the holder. This lets you precisely adjust the strength and direction of the polarizing effect to achieve the desired outcome for your specific scene.
German optical glass, like that from SCHOTT, is renowned for its clarity, consistency, and minimal distortion. This ensures true light transmission and maximum sharpness in your images.
This 86mm CPL filter is primarily designed for integration into a 100mm square filter holder. If your lens has an 86mm filter thread, you can mount it directly, but its optimal use case is within the holder system for versatility and compatibility with other 100mm filters.
The filter works by blocking polarized light waves, which are often responsible for glare and washed-out colors. By filtering these out, it allows more direct light to reach the sensor, resulting in deeper colors and greater contrast between tones.
This means the filter is highly effective at removing glare and reflections, leading to significantly improved contrast and color fidelity in your images, especially in bright conditions.
Urth has a program where each purchase helps fund local communities to plant 5 trees in areas impacted by deforestation, contributing to reforestation efforts.
Ensure you are using the correct size filter or step-up ring. Check for any debris in the lens threads or filter threads. Do not force the filter; re-align and try again.
Ensure the filter is correctly seated in the holder and that the rotating ring is properly engaged. Try rotating the filter to a different position. Note that CPL filters are most effective at a 90-degree angle to the light source.
This is normal as CPL filters reduce light transmission by approximately 1-2 stops. Adjust your exposure settings accordingly (e.g., increase ISO or shutter speed).
This filter is designed for 100mm systems. If using a very wide-angle lens (equivalent to 24mm or wider on full-frame) directly with the 86mm thread, vignetting may occur due to the filter thickness and lens hood. Using it within a 100mm holder may mitigate this, but check compatibility with your specific wide-angle lens and holder setup.
Setup: This 86mm CPL filter is designed to be used within a 100mm square filter holder system. Mount your 100mm holder onto your lens (using the appropriate step-up rings if necessary for your lens thread size). Then, slide the Urth 86mm CPL filter into the designated slot within the holder. The rotating adapter allows you to twist the filter element to achieve the desired polarizing effect.
Compatibility: The 86mm thread size is intended for direct mounting onto lenses with an 86mm front filter thread, but its primary integration is within a 100mm square filter holder. Ensure your lens has an 86mm thread, or use compatible step-up rings to attach it to the holder if your lens thread is smaller.
Care: To maintain optical quality, clean the filter regularly. Use a soft brush to remove dust. For smudges or fingerprints, use a microfiber lens cloth and a small amount of lens cleaning solution applied to the cloth, not directly to the glass. Avoid abrasive materials or harsh chemicals. Store the filter in its protective case when not in use.
