What this filter does

This 43 mm circular polariser removes unwanted reflections from non-metallic surfaces such as water and glass while boosting colour saturation and contrast in outdoor scenes. It is designed for photographers who want deeper blue skies and clearer detail without glare.

How it fits your kit

The ultra-slim 5.3 mm frame prevents vignetting on wide-angle lenses and the CNC grip pattern makes installation and removal easy. The filter threads onto any lens with a 43 mm front thread; verify the Ø marking on your lens barrel before ordering.

Coatings and handling

Double-sided 28-layer multi-coatings repel water, oil, dust and scratches so the glass stays clean in normal use. The lightweight aluminium-magnesium alloy frame resists jamming during rotation, letting you dial in the polarisation angle smoothly.

Questions about this item

How does the 5.3 mm ultra-slim frame prevent vignetting on wide-angle lenses?

The thin 5.3 mm rim profile avoids corner shading on wide-angle glass while still allowing full rotation to adjust the polarisation effect.

Will the 28-layer multi-coating resist heat and fingerprints during all-day outdoor shooting?

The hydrophobic, anti-oil and anti-dust coatings repel moisture and skin oils, so the glass stays clean and clear through extended use in warm conditions.

My lens shows Ø43 — will this filter thread directly onto it?

Yes, the 43 mm thread matches lenses marked Ø43; verify the diameter symbol on your lens barrel or cap before ordering.
