This Haida M10 Professional Filter Kit includes four filters that can be used individually or in various combinations to improve the results of your photography by preventing overexposure, as well as a circular polarizer to prevent distracting reflections or glare.
To allow these filters to be placed in front of a lens, this kit contains four filter holder adapter rings as well as a Haida M10 Filter Holder. The filter holder is designed to allow for the convenient use of up to three 100mm wide, 2mm thick filters along with the kit's drop-in circular polarizer filter. A filter bag is also included for the storage and transport of the kit.
Pre-installed with two pairs of plastic filter slots, the M10 Filter Holder is initially configured to accommodate two rectangular filters. Use of the filter holder can be easily accomplished by first screwing one of the included filter holder adapter rings onto a lens. While this filter kit provides adapter rings for lenses with 67mm, 72mm, 77mm, or 82mm front filter threads, separately available adapter rings allow the filter holder to be used with lenses that have 37mm, 39mm, 40mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, or 62mm front filter threads. After being fitted onto an adapter ring, the filter holder's push-and-release locking lever helps to create a reliable, yet adjustable connection that allows the holder to be rotated 360°, further benefiting the use of graduated neutral density and other filters that are enhanced by varied positioning. To help prevent stray light, which could have unwanted effects on exposure, from coming in-between an installed filter and a connected lens, two gaskets are included along the front of the M10 Filter Holder. These gaskets are positioned so that together, they form a seal between the filter holder's slots.
The M10 Professional Filter Kit's drop-in circular polarizer filter is mounted within a geared filter ring assembly with an external dial, which allows for the independent rotation of the circular polarizer filter in order to adjust the intensity of its effect. For still images or video captures where this filter is not in use, a drop-in cover is provided to occupy the filter holder's accessory slot for that filter. The cover then serves to prevent stray light from coming in-between the filter holder and the lens behind it.
The Haida 100 x 100mm Red Diamond Neutral Density 3.0 Filter and the 100 x 100mm Red Diamond Neutral Density 1.8 Filter are each solid neutral density filters for a respective 10-stop and 6-stop exposure reduction. Their densities create 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 or increasing your aperture, you are able to control depth of field and convey movement more easily.
The Haida 100 x 150mm Red Diamond Medium-Edge Graduated Neutral Density 0.9 Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a medium-edged line of transition between the dense and clear areas. A neutral density filter with a medium-edged line of transition can filter the sky while minimizing its effect on the land. It is particularly useful for images that include elements like rooftops and mountains that protrude into the sky. Neutral density filters do not affect the coloration of the image and this filter provides up to a 3-stop reduction in light from entering a lens.
The 100 x 150mm Red Diamond Hard-Edge Reverse-Graduated Neutral Density 0.9 to 0.3 Filter from Haida can be applied to darken bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image. Its effect is achieved with a 0.9 band of density across its center region that provides a 3-stop reduction in light from entering a lens. This band extends approximately 15mm in both vertical directions. With a soft-edged line of transition, it tapers to a 0.3 density that provides a 1-stop reduction in light at the edge above it. Directly below the 0.9 band of density, it tapers to clear, with a hard-edged line of transition before the clear area.
The placement of a 0.9 band of density that tapers to a density of 0.3 above it with a clear area directly below allows the Haida 100 x 150mm Red Diamond Hard-Edge Reverse-Graduated Neutral Density 0.9 to 0.3 Filter to match the positioning of the sun when it is at, or immediately above, the horizon. In such instances, the sun can appear closer to the center of an image as opposed to the upper edge, and an increase in brightness is created that is more prominent on both sides of the sun than above it. This pattern of brightness corresponds to the density pattern on the Haida 100 x 150mm Red Diamond Hard-Edge Reverse-Graduated Neutral Density 0.9 to 0.3 Filter. The hard-edged line of transition in this reverse, graduated neutral density filter is useful for hard transitions between the sky and land, while the 3- to 1-stop gradation with a soft-edged line of transition is applicable to multiple regions of brightness within the sky.
Haida Red Diamond filters are constructed from shock-resistant optical glass. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes 10 layers of anti-reflective nano coatings. An additional 10 scratch-resistant hydrophobic coatings further protect a Haida Red Diamond filter's substrate and result in an improved beading effect when its surfaces come in contact with water or oil, allowing for more efficient cleaning. Additionally, Haida Red Diamond filters feature rounded edges for easier placement within a compatible filter holder slot.
For each of this kit's rectangular filters, a light blocking gasket is included. These gaskets form a seal that is intended to prevent stray light, which could have unwanted effects on exposure, from coming in-between the filter and the lens behind it.
To enable the use of three rectangular filters along with the circular polarizer filter, an additional pair of filter holder slots is also provided.
