Urth Magnetic Circular Polarising (CPL) Lens Filter Plus+ - 43mm

A Circular Polarizing (CPL) filter reduces reflections and glare from non-metallic surfaces like water and glass. It also enhances color saturation and contrast, making skies bluer and foliage greener.

Yes, the Urth Magnetic CPL Filter Plus+ requires a specific Urth magnetic adapter ring to attach to your lens. The adapter ring is typically included with the filter.

Check the filter thread size printed on the front of your camera lens. This number (e.g., 55mm, 72mm) indicates the size of filter you need. The magnetic adapter ring will also be specific to this thread size.

While the magnetic system is designed for quick attachment, stacking multiple magnetic filters might be possible if they are designed to connect magnetically. However, stacking can increase the risk of vignetting and may affect optical quality. It's best to use one filter at a time for optimal results.

Use a soft, lint-free microfiber cloth to gently wipe the surface. For tougher smudges, a small amount of lens cleaning solution on the cloth can be used. Always avoid direct contact with the glass with fingers and harsh chemicals.

The Urth Magnetic CPL Filter Plus+ features an ultra-slim rim to minimize vignetting. However, with extreme wide-angle lenses, some slight darkening at the corners might still occur. It's recommended to test the filter on your specific lens.

German SCHOTT glass is renowned for its high quality, purity, and consistency, providing exceptional optical clarity, color fidelity, and light transmission compared to lower-grade glass.

Ensure you are using the correct Urth magnetic adapter ring for your lens and that it is securely screwed onto the lens thread. Check for any debris on the adapter ring or filter magnet.

While the rim is ultra-slim, very wide-angle lenses can still exhibit slight vignetting. Try zooming in slightly or check if the filter is properly seated. If the problem persists, the filter may not be compatible with the extreme wide-angle coverage of your lens.

Ensure the filter and lens are clean. Check that the filter is properly seated on the adapter ring. Clean the SCHOTT glass with a microfiber cloth. Avoid touching the glass surface.

The filter's polarization effect is adjustable by rotating the filter. Turn the outer ring of the filter to find the desired level of reflection reduction or color enhancement.
