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.
- - 【Ultra-thin Brass Frame】The frame is made of brass material with an ultra-thin design. CNC integrated molding has both hardness and flexibility, smooth and durable installation, 0.01mm-level processing accuracy, the frame is highly fitted and fixed to the lens, and there is no vignetting when installed on wide-angle and telephoto lenses.
- - 【Ultra-high light transmittance】The lens uses K&F Concept's exclusive coating technology, and the reflectivity as low as 0.15% guarantees 99.9% light transmittance. Ensures zero color cast and zero quality loss, reduces flare and ghosting that can occur when filters are attached to the lens, and has virtually no impact on the original performance of the lens
