Haida Rear Lens Clear-Night Filter for Canon EF/Tamron SP/Sigma/Samyang AF Lenses

The Rear Lens Clear Night Filter from Haida is designed to reduce light pollution in nighttime photography, allowing you to capture the beauty of the nighttime setting. The adapter ring is required to use the clear night filter with the exception of the Sigma 14-24mm f/2.8 DG DN Art Lens for Sony E and Leica L. It is designed for the Canon EF 17-35mm f/2.8L USM, EF 17-40mm f/4L USM, EF 11-24mm f/4L USM, and EF 16-35mm f/2.8L USM. Light pollution occurs in areas of the night sky that are above or near concentrated and intense sources of artificial light, such as cities. These sources can include streetlamps, exterior and interior lamps for commercial or residential buildings, sports and entertainment venue lighting, and brightly lit advertisements such as billboards. The Clear-Night Filter is a rear-mounted filter that can improve the results of nighttime images by absorbing the yellow light from sodium-vapor lamps, a common light source within urban areas. By preventing the dominant wavelengths of light associated with the color of those lamps from being recorded, the filter enhances visibility of astronomical objects. 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. A plastic case is included for storage and transport. 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.
