About this item

• 【ND Filter】Can be adjusted from ND8 to ND2000 (3-11 f-stop). Enables increased exposure times and/or apertures while using the neutral density filter to prevent overexposure.
• 【Multi Coating】Made of premium Japan Optics Glass. Double multi-coating, water repellent. Reduces the intake of light without affecting the overall color balance.
• 【Ultra Slim】Ultra slim rim design preventing wide angle vignetting. Extra tough aviation aluminum frame ensuring durability and jamming prevention.
• 【Easy Installation】This variable ND filter frame is designed with CNC trapezoidal pattern, ensuring more friction when screwing. Very easy to install.
• 【Note】Compatible with all 82mm lenses. Please verify your camera's lens thread size(usually marked somewhere on the lens barrel or printed underneath the lens cap) before ordering.This number is always preceded by a "Ø" (diameter) symbol. For example: Ø82 = 82mm lens thread size.

K&F Concept Variable Neutral Density Filter ND8-ND2000

ND------Extend exposure time. Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.

Explanation of "X" cross issues: "X" cross on images is a common issue with wide angle lenses and variable ND filters. Physics limit the capabilities of variable ND filters on wide angle lenses. When you enter the edge of the max range,the "X" issue may appear on your image. due to the particular angle of the two polarizers when approaching max density.

Note: The front diameter is larger than the back diameter of this filter. For example, Back thread (attach to lens): 82mm. Front thread (attach additional filter/other accessories): 86mm.

 

Variable ND Filter Functions

• Suitable for video shooting, large aperture prevents exposure, sunrise and sunset, sea forest, small river in Linne, long exposure, pedestrian traffic, traffic flow, foggy lake surface, light painting creation, but black crosses will appear for wide-angle lenses at high-end.
• Neutral density can be adjusted from nd8 to nd2000, easy to create different neutral density by rotating the ring.
• Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects.
• Decrease the depth of field by using wider apertures, which helps separate subjects from their background

How does it work? Made with the professional quality of Japanese optics and the precision of ND coating, it allows 2% light transmission, which means a reduction of 3 to 11 f-stops to achieve the desired light attenuation , offering superb image sharpness and perfect color neutrality.	Ultra Thin Frame The thickness of the frame is 7.5mm, and the surface is designed with a CNC trapezoidal pattern to ensure that the friction is increased over a large area when the user rotates.	Choose the right size Please verify your camera's lens thread size(usually marked somewhere on the lens barrel or printed underneath the lens cap) before ordering.This number is always preceded by a "Ø" (diameter) symbol. For example: Ø82 = 82mm lens thread size.
