Circular polarising camera filter Hoya CIR-PL 52 mm

Hoya CIR-PL Circular polarising camera filter (52 mm) reduces reflections from non-metallic surfaces and increases color saturation and contrast. It is suitable for landscape and outdoor photography where deeper skies and clearer water or glass surfaces are desired. The filter is made of high-quality optical glass and is designed to maintain overall color balance while minimising light loss. It can be rotated on the lens to control the degree of polarisation and refine the final image.

Advantages

The circular polarising filter removes unwanted reflections from water, glass and other non-metallic surfaces while enhancing color saturation and contrast without shifting overall color balance. Its 52 mm thread size fits compatible lenses and the rotating mount allows precise adjustment of the polarising effect. Constructed from optical-quality glass, the filter keeps image clarity and reduces stray light for reliable results.

Suitable for

• Landscape photography — deepening blue skies and increasing cloud contrast
• Water and seascape shots — reducing surface reflections to reveal details
• Glass and window photography — removing glare and improving visibility
• Outdoor portrait and travel photography where reflections are an issue

Key specifications

• Type: Circular polarising (CIR-PL)
• Thread size: 52 mm
• Material: Optical-quality glass
• Effect: Reduces reflections, increases saturation and contrast
• Manufacturer: Hoya, MPN Y1POLCSN52

How to use

Screw the filter onto a lens with a 52 mm front thread. Point the camera at the scene and rotate the filter while observing the viewfinder or live view until the desired reduction in reflections and increase in saturation is achieved. For cameras with beam-splitting metering or autofocus systems, use a circular polariser (CIR-PL) rather than a linear polariser to avoid exposure or focusing inconsistencies. Remove the filter when it is not needed to avoid unnecessary light loss.

Usage recommendations

Use the Hoya CIR-PL filter primarily for outdoor and landscape work in bright daylight; the polarising effect is strongest at a 90° angle to the sun. Avoid relying on the filter for low-light situations where any light reduction may require higher ISO or slower shutter speeds.
