Base Filter Kit Pro

Witness the Difference

No Filter

CPL Pro

Minimises reflections from water, glass and other reflective surfaces to reveal more detail and texture.

No Filter

CPL Pro

Maintains true colour accuracy — ensuring images stay clean and natural.

No Filter

Deepens contrast to revive flat or washed out scenes — skies darken, clouds pop and colours are more dimensional.

CoraNano™ Max Coating

34-layer nano-coating engineered for ultra-high light transmittance, ultra-low reflectivity, true-to-life colour neutrality and advanced resistance to water, oil and fingerprints.

AERO-C10™ Lens Shield

Our AERO-C10™ glass is ionically tempered for up to 600% stronger and 200% more scratch-resistant lens protection without any image distortion.

Unparalleled Optical Performance

Strength meets world-class optics with the UV Pro — over 99.13% light transmission and under 0.15% reflectance means pure light with zero compromise.

Aerospace-Grade Frame

Precision-machined from aerospace-grade aluminium, the ultra-slim frame is both lightweight and exceptionally strong.

CoraNano™ Max Coating

34-layer nano-coating engineered for ultra-high light transmittance, ultra-low reflectivity, true-to-life colour neutrality and advanced resistance to water, oil and fingerprints.

Unparalleled Polarisation

Industry-leading control and glare reduction on water, glass and reflective surfaces, with <0.5% reflectance and True Color transmission for unmatched detail and fidelity.
