Camera lens polarising filter Kenko 43 mm (model 234395)

The Kenko 43 mm polarising filter (model 234395) is a circular polariser designed to reduce reflections and glare, improve colour saturation and increase contrast in outdoor and through-glass photography. Sized for lenses with a 43 mm filter thread and finished in black, this single-piece filter also effectively blocks UV light below 370 nm without requiring exposure compensation, making it suitable for bright, high-UV environments such as mountains, beaches and snowy areas.

Advantages

This circular polarising filter reduces unwanted surface reflections from non-metallic surfaces and deepens blue skies while preserving natural colours. It helps to cut through atmospheric haze and increases image clarity, especially in scenes with water or glass. The filter’s design allows rotation to control the polarising effect, enabling fine adjustment of saturation and contrast without altering camera exposure settings.

Suitable for

• Landscape photography to enhance skies and foliage contrast
• Travel and outdoor photography where reflections from water or glass are common
• Photographing scenes with high UV levels such as snowy or coastal locations
• Situations requiring reduced glare for clearer subjects through windows or water

Key specifications

• Type: Circular polarising filter
• Filter thread diameter: 43 mm
• Colour / finish: Black
• Units included: 1 piece
• UV blocking: effective for wavelengths shorter than 370 nm
• Exposure compensation: not required under normal use

How to use

Screw the filter onto the front of any lens with a 43 mm filter thread until it is secure. Rotate the outer ring while observing the viewfinder or live view to adjust the degree of polarisation and achieve the desired reduction in reflections and increase in colour saturation. For best results, use the polariser at a 90-degree angle to the sun for maximum sky darkening and enhanced contrast. No additional exposure compensation is normally necessary, but always verify the camera’s metering in mixed lighting conditions.

Usage recommendations

Use the polariser when shooting landscapes, water scenes, or through glass to minimize reflections and enhance colours. Store the filter in a padded case when not in use to avoid scratches and keep threads clean to ensure smooth mounting and removal.
