K&F Concept Μεταβλητό Φίλτρο ND ND8-ND128 52mm

The K&F Concept Variable ND Filter ND8-ND128 is a high-quality neutral density filter designed for photographers seeking creative control over exposure and depth of field. With a variable density range from ND8 to ND128 (3-7 stops), this filter allows you to achieve long exposures and smooth motion effects even in bright conditions. Crafted with Japanese AGC optical glass and 28 multi-layer coatings, it ensures excellent light transmission, minimal color shift, and protection against scratches, water, and oil.

Advantages

This variable ND filter offers seamless adjustment of light reduction without the need to carry multiple fixed ND filters. Its ultra-slim aviation aluminum alloy frame minimizes vignetting on wide-angle lenses. The advanced coating technology reduces flare and ghosting, while the neutral color balance preserves natural tones. Designed to minimize X-pattern at maximum density, it delivers consistent performance across the entire range.

Suitable for

• Landscape photographers capturing silky waterfalls, smooth clouds, or motion blur
• Videographers needing precise exposure control in changing light
• Portrait photographers using wide apertures in bright sunlight
• Architectural and travel photographers seeking creative effects
