This 6-stop Drop-In K-Series ND and Circular Polariser Filter from H&Y Filters combines a solid neutral density effect with a circular polariser effect. It is made specifically to fit between a separately available H&Y Filters 100mm K-Series Filter Holder and one of the filter holder's adapter rings. Its 1.8 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time, you can create images with motion blur or by opening up your aperture to create shallow depth of field.

Simultaneously, this filter can help reduce reflections and glare by filtering out light that has become polarised due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarised due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarising filter arranges and filters this directionally polarised light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polariser only differs from a linear polariser in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarise the linearly polarised light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polariser, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarised, it permits the use of these functions.

Drop-In K-Series Neutral Density 1.8 and Circular Polariser Filters are constructed from Schott B270 glass for increased optical clarity and colour fidelity. They are mounted within a geared aluminium-alloy filter ring assembly with an external dial, which allows for the independent rotation of the filter in order to adjust the intensity of its polarization effect. Each side of this filter includes eight layers of anti-reflection coating to prevent internal ghosting and reflections as well as an anti-smear nano coating for an improved beading effect when in contact with water or oil for greater cleaning efficiency.

H&Y Filter Drop-in (95mm) Filters

The H&Y Filters NDHD MRD 95mm Drop-In Filter is designed for use with the RevoSwift 95mm Drop-In Filter Rack, a Modular (B) component of the RevoSwift system, these filters offer seamless integration and quick swapping without disrupting your setup. The Modular (B) filter rack also supports additional Modular (C) accessories such as the RevoSwift Magnetic 100mm Filter Holder, RevoSwift Magnetic Matte Box, and Swift Lens Hood.

When to Use Neutral Density (ND) + Circular Polariser Filters (CPL)?

Neutral Density (ND) + Circular Polariser filters (CPL) are essential for controlling exposure, reducing reflections, and achieving specific creative effects. Here’s a guide on when to use each type:

ND64 + CPL: Best for long exposure shots to create motion blur effects while enhancing colours and reducing reflections.
