Lens Filters
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.
- - 【Material】 ND Filter: Made by Completed Professional Optical Glasses instead of Optical Resin. filter reduces the intake of light without affecting the overall color balance.For this 105mm ND filter,the lens cap/hood should be 112mm. Because of the update of the product's package, the new and the old version will be sent randomly.
- - 【No “X” cross on images】Say goodbye to the "X" cross on images, K&F utilize cutting edge technology you're going to say goodbye to this common issue with wide angle lenses and variable ND filters.
- - It can cooperate with the bracket system to achieve 9 levels of light reduction, effectively reduce or eliminate the reflection of non-metallic surfaces, improve the clarity of the picture and effectively increase the color saturation, recommended for video and picture shooting
- - Using AGC Japanese optical glass, 36-layer nano-coating technology; double-sided polishing process, presenting high-definition lossless image quality
