Irix Revo CPL 77mm circulair polarisatiefilter

The Irix Revo CPL 77mm is a circular polarizing filter that cuts through reflections and atmospheric haze to deliver deep blue skies, rich foliage, and crystal-clear water. Its 16-layer multi-coating (8 per side) suppresses flare and ghosting while repelling water, oil, and dust, keeping your lens protected and your images contrast-rich even in challenging light.

Advantages

High-quality optical glass with 16 anti-reflective, hydrophobic, oleophobic, and scratch-resistant coatings ensures maximum light transmission and colour neutrality. The slim 4.3 mm aircraft-grade aluminium frame prevents vignetting on wide-angle lenses, while the front thread allows stacking of additional filters or a standard lens cap. Light reduction of 1.5–2 stops gives you precise control over exposure and motion blur.

Suitable for

• Landscape and outdoor photography to deepen blue skies and enhance foliage
• Architectural and automotive shots to reduce glass and metal reflections
• Water and nature scenes to cut through surface glare and reveal underwater detail
• Any lens with a 77 mm filter thread, including wide-angle zooms and primes

Recommendations

For best results, rotate the filter ring while looking through the viewfinder to find the polarisation angle that maximises sky saturation or minimises reflections. Pair with a lens hood to further reduce stray light, and clean the filter with a microfiber cloth – the oleophobic coating makes fingerprints easy to remove.
