K&F Concept Nano-Klear phone clip with magnetic CPL polarising filter 49 mm

Nano-Klear — a phone clip with a magnetic 49 mm CPL polarising filter. The filter holds on the clip by magnet, so it goes in front of the phone camera and comes off in one move. It suppresses reflections on glass and water and deepens blue skies and greenery. Before buying, check that 49 mm covers your phone’s lenses.

A polarising filter removes reflections from non-metallic surfaces — shop windows, water, wet tarmac or leaves. Turning the filter sets how strongly it works, so the sky darkens and greenery gains saturation while shooting, not later in editing. The glass has an HMC multi-layer anti-reflective coating. The filter attaches to the clip ring by magnet, so it comes off quickly when not needed while the clip stays on the phone.
