Hoya YYP4177 HD Nano MkII 77mm Circular Polarizing Filter

The Hoya HD Nano MkII 77mm Circular Polarizing Filter is built for photographers who refuse to compromise image quality for the sake of glare control. Whether you're deepening blue skies in landscape work, cutting reflections off water or glass in architectural shoots, or saturating autumn foliage colors, this filter does its job while staying nearly invisible in the optical chain. The 25% greater light transmission compared to standard polarizing film means you lose roughly half a stop less light than a conventional CPL — a tangible advantage when you're shooting handheld in forests, overcast conditions, or any scenario where shutter speed matters.

Build quality reflects Hoya's professional-tier engineering. The 16-layer nano coating applied to both glass surfaces creates an ultra-hard, ultra-smooth finish that resists scratches at twice the rate of standard optical coatings. In practice, this means confidently wiping the filter with a microfiber cloth in the field without worrying about micro-abrasions degrading performance over time. The water and oil-repellent properties keep the glass shooting-ready in rain and humid conditions. The slim aluminum frame threads cleanly onto 77mm lenses and retains front threads for caps or additional filters, making it a practical, always-on option for photographers who prefer to leave their polarizer mounted throughout a session.
