●【NO "X" CROSS ON PICTURES】Say goodbye to the "X" cross on pictures, K&F uses state-of-the-art technology, you will say goodbye to this common problem with wide angle lenses and variable GND filters.
●Professional design: ultra-thin rim design prevents vignetting at a wide angle. Extra robust aviation aluminium frame ensures durability and prevents blocking.
●Nanotec: Our optical engineers have developed a new nano coating technology, a waterproof, scratch-resistant, anti-reflective green coating that effectively protects against oil, fingerprints and scratches and protects the valuable lens.
●Material: ND filter: made by completed professional optical glasses instead of optical resin. Filter reduces light absorption without affecting the overall colour balance.
●Note: Please check the lens thread size of your camera before ordering (usually marked somewhere on the lens barrel or printed under the lens cap). The number is always preceded by a "ø" (diameter) symbol.

Description
1. When shooting outdoors, the light difference between the sky and the ground is often very different. Due to the limited scope of the photosensitive component of the camera, it is impossible in this case to take pictures with normal exposure of the sky and the ground at the same time. So that the sky can be exposed accurately, the ground is underexposed and pitch black. To ensure that the ground can be exposed accurately, the sky is underexposed and empty. Soft gradient is semi-transparent and semi-gradient grey to achieve partial darkening, balance the light condition and avoid overexposure of highlights. It is one of the commonly used filters in landscape photography. (Product features: suitable for high contrast between the sky and the ground. If the floor exposure is normal, the sky is greatly overloaded. The soft gradient lens can effectively balance the light and contrast.)
2. On the raw material of the optical glass, precision grinding and double-sided polishing ensure the stability of the molecular structure and do not affect the sharpness of the telephoto lens, ensuring high-resolution imaging.
3. After the glass has been polished optically, a high-tech film is plated on the surface: "mildew proof", "waterproof", "scratch resistant" and "anti-grease". It does not affect the image quality and can be easily removed, even if it is contaminated with water drops or oil stains.
4. High-tech technology for gradual coating, uniform and stable colour, precise gears that ensure no deviations in dimming and perfect image quality.
5. Soft gradual GND16 round filter, dimming 3 levels (0.9), transmission of 12.5%, reflectivity of 1.5%, the anti-reflection rate of the same level in the industry is only 2%, and the plastic resin is up to 4.5%.
