Product Information

Full details

The Urth Circular Polarising Filter Plus+ 82mm is designed for professional creators seeking superior image quality and glare reduction. Its key benefit is enhancing contrast and color saturation by minimizing reflections, though its advanced coating may require specific cleaning methods. This filter utilizes German Schott glass and a 20-layer dual-side coating to reduce reflections, cut polarized light, and boost color vibrancy for natural, glare-free results.

FAQs

What is the main benefit of a Circular Polarising Filter?

A CPL filter reduces glare and reflections from non-metallic surfaces like water, glass, and foliage. It also increases color saturation and contrast, especially in skies.

How do I know if this filter will fit my lens?

This filter has an 82mm thread size. Check the diameter number printed on the front of your lens (often preceded by a circle with a slash through it, e.g., Ø82mm). If your lens has a different thread size, you may need a step-up ring.

Can I stack this filter with other filters?

Yes, the filter features a double-threaded rim, allowing you to stack it with other filters (like ND or UV filters) or attach a lens cap.

How should I clean the filter's coating?

Use a soft microfiber lens cloth. For tougher smudges, lightly dampen the cloth with a specialized lens cleaning solution. Avoid applying cleaner directly to the filter. Always remove loose dust with a blower first.

Does the 20-layer coating affect image quality?

No, the CoraNano 20-layer coating is designed to enhance image quality by providing high light transmission for sharper images, finer colors, and greater depth, while also offering protection.

What is the difference between a Circular Polariser and a Linear Polariser?

Circular Polarizers (CPL) are recommended for modern DSLR and mirrorless cameras with autofocus and metering systems, as they do not interfere with these functions. Linear Polarizers can cause issues with these systems.

What does 'vignetting' mean in photography?

Vignetting refers to the darkening of the image corners, often caused by lens hoods or thick filter rims obstructing light. The ultra-slim rim of this filter is designed to minimize this effect.

Troubleshooting

Filter causes extreme darkening of the image

Ensure the filter is a Circular Polariser (CPL) and not a Linear Polariser if using with modern autofocus cameras. Check that the filter is screwed on correctly and is not overly dense.

Visible vignetting (dark corners) in photos

The ultra-slim rim is designed to minimize this, but on very wide-angle lenses, some vignetting might occur. Try removing any stacked filters or using a lens hood to see if the issue persists. Consider a wider lens or a filter designed for extreme wide-angle use if the problem is severe.

Difficulty rotating the filter to adjust polarization

Ensure the filter is not cross-threaded onto the lens. Check for any debris on the lens threads or filter threads. If it feels stiff, try unscrewing and re-screwing carefully.

Image colors appear unnatural or shifted

This can sometimes happen with strong polarization. Adjust the filter's rotation to find a more natural color balance. Ensure your camera's white balance is set correctly.

Setup, Compatibility & Care

Setup:

  1. Ensure your lens has an 82mm filter thread. If not, an appropriate step-up ring will be required.
  2. Gently screw the Urth Circular Polarising Filter Plus+ onto the front of your lens clockwise until snug. Do not overtighten.
  3. To adjust the polarizing effect, rotate the front ring of the filter while looking through the viewfinder or at your live view screen until the desired level of glare reduction or contrast enhancement is achieved.

Compatibility:

  • Lens Size: This filter is designed for lenses with an 82mm front filter thread. Check your lens specifications for compatibility.
  • Stacking: The double-threaded rim allows for stacking with other filters (e.g., ND filters) or attaching lens caps.

Care:

  • Cleaning: For best results, use a lens blower to remove dust. For smudges or fingerprints, use a microfiber lens cleaning cloth. For stubborn marks, lightly dampen a corner of the microfiber cloth with a dedicated lens cleaning solution (avoid spraying directly onto the filter).
  • Storage: Store the filter in its protective case when not in use to prevent scratches and dust accumulation.
  • Handling: Avoid touching the glass surface directly. Handle the filter by its edges.
