King CPL 34mm Circular Polarising Filter

A circular polarizer filter with a 34mm thread, built to cut through glare and reflections while deepening colour intensity. Its multi-coated optical glass delivers crisp, neutral results across landscape and outdoor scenes.

Advantages

The King CPL 34mm uses high-quality optical glass with multi-coating to suppress unwanted reflections from water, glass, and foliage. The slim aluminium frame keeps vignetting at bay on wide-angle lenses, while the double-threaded design allows stacking additional filters or a lens cap. A water-resistant and scratch-resistant coating protects the filter in challenging conditions, and the anti-fingerprint layer makes cleaning effortless.

Suitable for

• Landscape photography to darken blue skies and boost contrast
• Shooting through glass or water without distracting reflections
• Outdoor work in dusty, damp, or high-glare environments
• Lenses with a 34mm filter thread, including many compact and mirrorless systems
