K&F Concept Säädettävä ND-suodatin ND3-ND1000 49mm

The K&F Concept Variable Neutral Density Filter offers photographers and videographers precise control over exposure by reducing light entering the lens from 1.5 to 10 stops (ND3-ND1000). This 49mm filter is crafted with Japanese AGC optical glass and 28 multi-layer coatings, ensuring waterproof, scratch-resistant, anti-reflection, and oil-proof performance. The ultra-slim aviation aluminum alloy frame features a smooth rotation mechanism with hard stops at MIN and MAX, preventing the X-pattern effect at maximum density. Ideal for achieving slower shutter speeds and wider apertures in bright conditions, this filter maintains natural color balance with no noticeable color shift.

Advantages

Versatile exposure control with a wide density range, high-quality optical construction for sharp images, and durable build for long-lasting use. The multi-coatings protect the glass and reduce flare, while the slim frame minimizes vignetting on wide-angle lenses.

Suitable for

• Landscape photography to create motion blur in waterfalls and clouds
• Portrait photography to use wide apertures in bright sunlight
• Videography to maintain proper shutter speed and cinematic motion blur
• Long exposure photography without carrying multiple ND filters
