Made of aluminum alloy for durability, the 100-PRO 100mm Filter Holder from Haida is compatible with 100mm filters with a thickness of up to 2mm. It comes equipped with three filter slots, allowing you to use different filters simultaneously to achieve a wide variety of effects. And even when stacking filters in front of a wide-angle lens, the holder avoids producing any noticeable vignetting in most cases.

On the rear side of the filter holder is a built-in gasket, which helps block light from entering the lens coupling. This allows you to take long exposure shots without worrying about any stray light ruining your image. Several sizes of adapter rings are available separately for different lenses, ranging from 49mm to 82mm, and need to be purchased for proper use.

This 67mm Adapter Ring from Haida allows you to use the Haida 100-PRO insert filter holder with any lens that has 67mm front filter threads. It can be screwed onto the lens first, allowing you to then easily mount the holder, and is made of aluminum for durability.

This 72mm Adapter Ring from Haida allows you to use the Haida 100-PRO insert filter holder with any lens that has 72mm front filter threads. It can be screwed onto the lens first, allowing you to then easily mount the holder, and is made of aluminum for durability.

This 77mm Adapter Ring from Haida allows you to use the Haida 100-PRO insert filter holder with any lens that has 77mm front filter threads. It can be screwed onto the lens first, allowing you to then easily mount the holder, and is made of aluminum for durability.

This 82mm Adapter Ring from Haida allows you to use the Haida 100-PRO insert filter holder with any lens that has 82mm front filter threads. It can be screwed onto the lens first, allowing you to then easily mount the holder, and is made of aluminum for durability.

This Haida NanoPro MC Circular Polarizer Filter is designed for use with the Haida 100-Pro Filter Holder. It helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized 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 polarizer only differs from a linear polarizer 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 polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This filter is constructed from optical glass for clarity and color fidelity. To prevent internal ghosting and reflections, each glass surface includes 10 layers of anti-reflection coatings, which also offer greater protection to the filter substrate and help keep it clean for a longer period of time. The Nano coating associated with this NanoPro MC Circular Polarizer Filter provides an additional layer that results in an improved beading effect when the surface comes in contact with water or oil, allowing for more efficient cleaning.

The Haida 150 Insert Filter Pouch is designed to provide a secure and convenient, transport and storage solution for any combination of up to six Haida 150 x 150mm or 150 x 170mm filters. Filters placed within this pouch are each held within one of six padded, nonabrasive slots. They can be easily accessed by opening its zippered closure and touch-tab fastened front flap which covers an outer pocket that can accommodate a Haida 150 filter holder kit.

When photographing with a tripod and a Haida filter system, a loop along the rear of the Haida 150 Insert Filter Pouch allows it to be draped over that tripod, putting your filters in more immediate reach. This pouch's exterior is woven from nylon for durability, and an adjustable, clip-on shoulder strap allows for over-the-shoulder carrying as well.
