Polarising camera filter Hoya HD Mk II 72 mm

HOYA HD Mk II CIR-PL 72 mm is a circular polarising camera filter designed to reduce reflections and enhance color contrast for clearer skies and more vibrant foliage. The filter uses a high-transparency, UV-absorbing polarizing film that provides approximately 25% better light transmission than standard polarizers, while preserving the same polarization effect. Built with HOYA’s reinforced HD optical glass and a low-profile metal frame, this 72 mm polariser is intended for outdoor and landscape photography where control over reflections and improved color saturation are required.

Advantages

The HD Mk II CIR-PL increases light transmission for nearly half a stop advantage versus standard polarizing films, improving contrast and clarity without altering color balance. Its circular polarizing design controls reflections from non-metallic surfaces—such as water and glass—making submerged details and interior scenes more visible. The filter features chemically reinforced HD glass for greater durability and a 16-layer anti-reflective multi-coating on both sides for reduced internal reflections, water- and oil-repellence, and easier cleaning. A low-profile frame and high-pressure mounting enhance sturdiness and compatibility with lens hoods.

Suitable for

• Landscape and nature photography to deepen skies and enhance foliage color
• Outdoor and travel photography to reduce glare from water and wet surfaces
• Architectural and street photography when shooting through glass or reflective surfaces
• General use with lenses that accept 72 mm screw-in filters

Key specifications

• Type: Circular polarizing filter (CIR-PL)
• Mount diameter: 72 mm
• Optical material: HOYA HD reinforced glass
• Polarizing film: High-transparency, UV-absorbing polarizing film (≈25% higher transmission than standard)
• Coating: 16-layer anti-reflective multi-coating, water- and oil-repellent

How to use

Screw the 72 mm HOYA HD Mk II CIR-PL onto the front of a lens with a matching filter thread. Rotate the outer ring while viewing the scene through the viewfinder or on the camera display to adjust the polarization effect; maximum suppression of reflections and maximum color saturation occur at specific rotation angles. Use the filter when shooting skies, foliage, water, or through windows to control unwanted reflections and increase color contrast. Check exposure after fitting the filter, as the polarizer can slightly reduce overall light reaching the sensor.

Usage recommendations

For best results, mount the circular polarizer on a lens with a 72 mm thread and rotate it while observing the scene to find the desired effect. Use in combination with a lens hood to minimize stray light. Avoid using strong polarisation on wide-angle shots where uneven sky darkening may occur; adjust exposure as needed to compensate for the filter’s light transmission characteristics.
