Neutral Density Filters
A neutral density filter (ND filter) is a filter of uniform density that attenuates light of all colors equally. An ND filter is used to allow a longer exposure (to create blur) or larger aperture (for selective focus) than otherwise required for correct exposure in the prevailing light conditions, without changing the tonal balance of the photograph.
A graduated neutral density filter is a neutral density filter with different attenuation at different points, typically clear in one-half shading into a higher density in the other. The ND filter can be used, for example, to photograph a scene with part in deep shadow and part brightly lit, where otherwise either the shadows would have no detail or the highlights would be burnt out.
- - 【ND & CPL filter 2 in 1】One filter has both of CPL and varaible ND filter function,save your time to replace two filters; it can not only reduce the amount of light entering the lens but also darken skies, manage reflections at the same time.
- - 【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.
- - 【ND Filter Function】The Variable ND filter main function is to reduce the entry of light without affecting the overall colour balance, for long exposure and motion blur techniques in changing light.
- - 【No X Cross & frame self-locking technology】Say goodbye to the "X" cross on images with K&F peak technology. The filter will stop when rotating to Mini (ND32) or Max (ND512).
- - The lens is made of top Japanese optical glass, and the lens is coated with 28 layers of nano-coating on both sides, which is waterproof, oil-proof, scratch-proof, and anti-fog. The lens adopts grinding and polishing technology on both sides to ensure ultra-high-definition, and the sharpness of the image is not damaged.
- - The frame adopts self-locking technology, which is infinitely rotated by 2-6 steps, which is convenient for light reduction and positioning, and at the same time avoids the phenomenon of black crosses. The frame is equipped with a push rod, which is convenient for customers to adjust the gear size. For users who shoot video, it is helpful to automatically adjust the light reduction gear through auxiliary tools.
- - 【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% ensures ultra-high light transmittance. 10-stop dimming ensures zero color cast and quality loss, reduces flare and ghosting that can occur when filters are attached to the lens, and has little impact on the original performance of the lens
