In photography and videography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path. The filter can be of a square or oblong shape and mounted in a holder accessory, or, more commonly, a glass or plastic disk in a metal or plastic ring frame, which can be screwed into the front of or clipped onto the camera lens. In digital photography the majority of filters used with film cameras have been rendered redundant by digital filters applied either in-camera or during post processing. Exceptions include the ultraviolet (UV) filter typically used to protect the front surface of the lens, the neutral density (ND) filter, the polarising filter and the infra red (IR) filter. The neutral density filter permits effects requiring wide apertures or long exposures to be applied to brightly lit scenes, while the graduated neutral density filter is useful in situations where the scene's dynamic range exceeds the capability of the sensor. Not using optical filters in front of the lens has the advantage of avoiding the reduction of image quality caused by the presence of an extra optical element in the light path and may be necessary to avoid vignetting when using wide-angle lenses.
- ND1000 effectively prevents more than light, interferes with the viewfinder, guarantees the quality of picture shooting, and can play a certain dust-proof and waterproof function, which is very suitable for shooting scenery.
- The material of the filter is top-level optical glass, which adopts double-sided multi-layer enhanced coating, which can effectively reduce the surface reflection of the filter. It greatly reduces the glare caused by the reflection of the outer line of the long-exposure lens, and ensures the first-class image quality.
- Soft gradient GND8 square filter, the size is square 100x150mm, the product weight is 47.5g, the lens thickness is 2mm, the applicable lens diameter is 98mm and below, the light reduction is 3 gears (0.9), the transmittance is 12.5%, The reflectivity is 1.5%. The GND8 square plate has excellent anti-reflective rate. The anti-reflective rate of the same level in the industry is only 2%, and the plastic resin is as high as 4.5%.
- The material of the 100mm system filter holder is made of aviation aluminum through CNC-integration processing, and the surface is black frosted and oxidized;
- Included 49/52/58/62/67/72/77/82, seven adapters, perfectly matched with the lens
- It is suitable for the contrast between the sky and the ground. If the ground exposure is normal, the sky will be severely overburdened. The soft gradient lens can effectively balance the light ratio and contrast.
- The material of the filter is top-grade optical glass imported from Germany. The quality is guaranteed, which is the standard for high-quality products.
- After the glass is optically polished, a high-tech film is plated on the surface. "Moldproof", "Waterproof", "Anti-scratch" and "Anti-greasy" While having the characteristics of hard scratching, it will not have any impact on the image quality, even if it is contaminated with water droplets or oil, it can be easily removed.

5. High-tech gradual coating technology, uniform and stable color, accurate gears, ensuring no deviation in dimming, and perfect pict
- It has the third characteristic of IR, anti-infrared cut-off, in order to reduce the redness of long-term exposure photos due to infrared light pollution, which will degrade the image quality. This product is coated with infrared cut-off film, which can effectively cut off infrared pollution. (This part is imaginary, in fact, it won't be available in this grade of series, but everyone writes it, it depends on your own choice)
