K&F Concept Nano-X ND8 49mm Neutral Density Filter

The K&F Concept Nano-X ND8 49mm Neutral Density Filter is a high-quality optical accessory designed for photographers seeking creative control over exposure. Crafted from Japanese AGC optical glass with 28-layer multi-coating, this filter reduces light by 3 stops (12.5% transmission), enabling slower shutter speeds or wider apertures in bright conditions. The ultra-slim 3.3mm aviation aluminum alloy frame is double-threaded for stacking multiple filters, and the coating is waterproof, oil-proof, scratch-resistant, and anti-reflective, ensuring no color shift and durable performance.

Advantages

This ND8 filter allows you to achieve motion blur in waterfalls, clouds, or traffic, and to use wider apertures for shallow depth of field in bright light. The multi-coating minimizes flare and ghosting, while the slim frame prevents vignetting on wide-angle lenses. The waterproof and oil-proof coating makes cleaning easy and protects against dust and moisture.

Suitable for

• Landscape photographers wanting silky water or cloud effects
• Portrait photographers needing wide apertures in sunlight
• Videographers requiring slower shutter speeds for cinematic motion blur
• Any photographer using lenses with a 49mm filter thread
