K&F CONCEPT 62mm Soft GND8 Lens Filter Graduated ND Neutral Density

Grad ND is suitable for large light ratio contrast and adds some darkness to specific parts of an image. For example, the sky can look darkened whilst the rest of the picture is bright. The soft gradient filter can effectively balance the light ratio and contrast. Top-grade optical glass: Precision grinding and double-sided polishing, it will not affect the sharpness and ensure high-definition imaging. Double-sided high-tech coating: Mold proof, waterproof, anti-scratch and anti-greasy; ensure uniform and stable colour, accurate gears, and there is no deviation in dimming, provide the best picture quality. Soft gradient GND8 circular filter, dimming 3 stops (0.9), transmittance 12.5%, reflectivity 1.5%, better than 2% of the same level in the market. The frame is made of aviation-grade aluminium, and only 5.3mm thickness. The design of the thin frame ensures that wide-angle end and the telephoto end will not have vignetting. The edges are designed with trapezoidal patterns to increase friction and facilitate installation and removal.
