Why choose the HOYA HD nano Mk II CIR-PL?
The HOYA HD nano Mk II CIR-PL is one of the most advanced polarizing filters available.
It features a High Transparency HD Polarizing Film, produced using high-pressure press technology for exceptional durability. The ultra-hard nano coating ensures outstanding resistance to scratches and stains, delivering long-lasting performance.
With the HD nano Mk II CIR-PL, you’ll achieve pristine image quality that meets the highest professional standards.
The strength of the the ultra-hard nano coating
The coating is the most fragile part of any filter, often wearing off with regular use and cleaning, which can degrade image quality.
The HOYA HD nano Mk II solves this with its ultra-hard nano coating, bonded to the glass at the nano level for maximum adhesion and density.
With 16 layers on both sides, it is up to 200% harder than standard CIR-PL filters, offering unmatched resistance to scratches and stains.

High transparency polarizing film for fast shutter speed
The HD nano Mk II CIR-PL uses a high-transparency polarizing film that offers 25% better light transmission than standard filters, providing nearly half a stop more light without compromising polarization, ideal for low-light shooting.

Control reflections
The HOYA HD nano Mk II CIR-PL enables optical effects impossible to reproduce in post-production. By filtering polarized light, it lets you control reflections on glass or water surfaces, revealing details beneath the surface and enhancing overall clarity.

Enhance contrast and color saturation
Polarized light is not limited to surface reflections, but light shining directly from the sky is polarized too. Air molecules, moisture and dust scatter sunlight, and this light can be filtered out with the HOYA HD nano Mk II CIR-PL. This allows you to greatly increase the contrast of the sky, removing haze, and enhancing blue hues.

Slim design with high stability
The HD nano Mk II CIR-PL features an ultra-thin aluminum frame, minimizing thickness and preventing vignetting even with most wide-angle lenses. The glass is secured using high-pressure press technology, ensuring exceptional stability, durability, and long-term reliability.
