• This Haida Rear Lens ND Filter Kit contains four filters that are each compatible with the built-in rear filter slot of a Sigma 14-24mm f/2.8 DG DN Art lens for Sony E-mount camera or a Sigma 14-24mm f/2.8 DG DN Art lens for a Leica L-mount camera.
• Each filter can be used individually to create a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control the depth of field and convey movement more easily.
• The kit's ND 0.9, ND 1.2, ND 1.8, and ND 3.0 filters provide a respective 3, 4, 6, and 10-stop exposure reduction. These filters are constructed from optical glass for clarity and color fidelity. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
• 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 these neutral density filters provides an additional layer that results in an improved beading effect if their surfaces come in contact with water or oil, allowing for more efficient cleaning.
• Please confirm the camera SLR lens brand type before ordering. Your camera's lens brand type will be marked somewhere on the lens barrel.If you have any questions about Haida products, you can contact us at any time
