Q&A
Q1: How does ND2-400 work?
A1: Two sets of polarizers with high transparency are used to control the amount of light entering the lens through the filter.
Q2: Can the original lens cap be used for ND2-400?
A2: In order to prevent vignetting, the ND2-400 is designed with an ultra-wide angle structure. The front port diameter of the filter is one size larger than the original aperture of the lens, so the lens cap needs to be one size larger than the lens aperture. For example, the 77mm ND2-400 Need to use 82mm lens cap.
Q3: Does ND2-400 have a color cast?
A3: Due to the use of polarizing film to control the amount of light entering, color cast is a common phenomenon among all adjustable NDs on the market. KF relies on mature manufacturing technology and fine coating technology to minimize the polarization effect of the polarizing film.
Q4: Does ND2-400 have vignetting?
A4: Using Nikon Z 7 and Nikor 14-30mm Sline test, 14mm vignetting is not obvious, 16mm has no vignetting.
Q5: Does ND2-400 have a cross shadow?
A5: The maximum aperture of an ultra-wide-angle lens below 24mm will have a slight cross shadow in the 1-5 gear dimming. The longer the focal length used, the smaller the effect of the cross shadow. There will be obvious cross shadows and vignetting in the large gear of dimming. If you continue to rotate the shadows, the shadows will disappear naturally, which is a physical phenomenon and not a product problem.
Functions of ND2-400
Functions of ND2-400
1. Under the premise of ensuring the best iso and not changing the aperture, the shutter speed can be freely changed according to the desired effect
2. Under the premise of maintaining the same shutter speed, a large aperture exposure can be used to create a blurred background effect
3. Even with a shutter speed of 1/8000 sec, the maximum aperture of F1.4 or F1.2 may cause overexposure. In this case, the ND2-400 can easily eliminate overexposure and retain highlight details.
4. Adjustable ND has more applicable ranges and applicable scenarios. If you pursue the ultimate picture quality, it is recommended to choose a fixed value ND.

From 1-5 stops, there will be a slight X cross for lens under 24mm. An X cross will appear at the highest stop and can be removed by rotating the filter ring, which is a normal situation instead of a quality issue.

To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction so the front side of the ND filter is one size larger than the camera lens. It is recommended to use a lens hood of a larger size.
