K&F Concept CPL Polarising Filter for DJI Osmo Action 3/4/5 Pro

CPL Polarising Filter for DJI Osmo Action 3/4/5 Pro. It earns its place in landscapes, by the water and when shooting through shop or car windows, where reflections otherwise drown colour and detail and the sky stays pale.

• 28 anti-reflective layers, reflectance 0.2 %
• The surface repels water and grease and resists scratches

No glare, deeper colour

A polarising filter takes the glare off water, glass and foliage, and with it brings out the colours that were hiding underneath. The sky darkens, clouds stand out, leaves stop flaring white and you can see through the surface of water. The effect is set by rotating the filter and is strongest at right angles to the sun; it cannot be recreated in post, because it is a property of the light rather than a colour in the file.

The glass carries 28 anti-reflective layers and reflects only 0.2 % of the light, so no ghosting or veiling appears against the light. The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field. The filter goes on over the original protective lens glass — that stays in place and the filter just snaps gently onto it. The camera gains practically no weight, so nothing changes on mounts or a helmet either.
