The NiSi UHC CPL filter incorporates 13 advanced multi-layer coatings, providing superior light transmission while effectively reducing reflections and glare. These coatings ensure that your images are sharp, clear, and vibrant, even in challenging lighting conditions. With high-precision polishing on both sides, the NiSi UHC CPL filter guarantees no loss of image sharpness, even when using high-resolution sensors. Capture every detail with 8K Ultra HD clarity, making it ideal for professional-level photography and videography.

Equipped with an ultra-durable coating, this filter offers exceptional scratch resistance, prolonging its lifespan and maintaining impeccable optical quality. Achieve superior polarisation efficiency with the NiSi UHC CPL filter. This high-performance filter reduces haze in landscapes, enhances colour saturation, and provides greater tonal contrast, delivering stunningly vibrant and clear images.

The ultra-thin, knurled design of the frame prevents vignetting on ultra-wide-angle lenses. Its slim profile ensures compatibility with a wide range of lenses without compromising durability or ease of use. Made from high-quality AGC glass, the NiSi UHC CPL filter offers excellent clarity and durability. This premium glass material guarantees optimal performance and reliability in various shooting environments.

The multi-nano coatings make this filter waterproof, oil-proof, and easy to clean. These properties ensure that the filter remains free of smudges, water drops, and dust, maintaining a clear view for the perfect shot every time. Additionally, the blackened edges of the NiSi UHC CPL filter reduce flare and minimise internal reflections, ensuring your images remain sharp and free from unwanted artefacts.

When it comes to enhancing images, a circular polarizer is probably the oldest trick in the book. It can change a pale sky to a deep blue one, turn foliage into a luminous super-green, light up autumn colours, saturate rainbows and even make water look crystal clear. The added contrast, saturation and clarity that a polarizer can give to images is nothing short of magic and every photographer should have one in their bag.

Contrary to its name, a polarising filter does not polarise light; it filters out polarised light. Light from the sun is polarised when it bounces off any non-metallic reflective surface like water, foliage or various air particulates. Polarised light robs images of colour, clarity and contrast and is in many situations undesirable. A polarizing filter removes this 'damaged' light and ensures that only unpolarised light reaches the camera sensor to produce a sharp, saturated and contrast-rich image.

For this reason, a polarizing filter is a very popular tool for any photographer, but especially for landscape photographers. 

What is the difference between a linear and circular polariser? Digital cameras' AF systems are not compatible with linear polarizers. When the world was transitioning from film to digital, linear vs. circular was a big debate, but it no longer is. For photographic purposes, you can assume that any polariser on the market nowadays is circular and not linear.
