K&F Concept Variable ND Filter ND3-ND1000 46mm Grey

The K&F Concept Variable Neutral Density Filter offers precise control over light exposure, allowing photographers and videographers to achieve creative effects such as motion blur and shallow depth of field even in bright conditions. With an adjustable ND range from ND3 to ND1000 (1.5 to 10 stops), this filter is ideal for long exposure photography, videography, and portraiture.

Advantages

This filter provides seamless adjustment of light reduction without the need to carry multiple fixed ND filters. The ultra-slim 5.5mm frame minimizes vignetting, while the 28-layer multi-coating ensures sharp, color-neutral images with reduced reflections and flare. The waterproof, scratch-resistant, and oil-proof coating makes it durable for outdoor use.
