Hoya YYP4172 72mm HD Nano MkII Polarizing Filter

The Hoya HD Nano MkII 72mm Circular Polarizing Filter represents the current top of Hoya's filter engineering, built for photographers who want polarization control without accepting the optical compromises that cheaper filters impose. The 16-layer ultra-hard nano coating applied to both glass surfaces achieves two things simultaneously: it maximizes light transmission — 25% more than standard polarizing film, translating to nearly half a stop of recovered light — and it hardens the surface to 200% greater scratch resistance than conventional optical coatings. In the field, this means cleaner images with stronger contrast, less flare in backlit conditions, and a filter surface that survives the realities of regular professional use without accumulating the micro-abrasions that soften images over time.

The slim aluminum frame is engineered to minimize vignetting on wide-angle lenses while retaining front threads for lens cap attachment or filter stacking. The water and oil repellent coating is not a gimmick — it genuinely reduces cleaning friction in humid, dusty, or coastal environments where a quick wipe needs to work the first time. Rotation is smooth and consistent, with enough resistance to hold its position once set. For photographers who keep a polarizer as a near-permanent fixture on landscape, architectural, or outdoor portrait lenses, the HD Nano MkII is the kind of investment that pays back in image quality and longevity across thousands of frames.
