Filtro ND variable K&F Concept ND3-ND1000 77mm

The K&F Concept Variable Neutral Density Filter (ND3-ND1000) is a versatile tool for photographers and videographers seeking precise exposure control. With a 77mm diameter and a variable ND range of 1.5 to 10 stops, this filter allows you to adapt to changing light conditions without swapping filters. Crafted from high-quality optical glass with multi-coatings, it ensures minimal color shift and excellent image clarity.

Advantages

This filter offers smooth, stepless adjustment from ND3 to ND1000, enabling creative long exposures and shallow depth of field in bright light. The advanced design minimizes the 'X' pattern often seen at high ND settings, while the ultra-slim aviation-grade aluminum alloy frame prevents vignetting on wide-angle lenses. Water-repellent, oil-resistant, and scratch-resistant coatings protect the glass and make cleaning easy.

Suitable for

• Landscape photographers capturing silky waterfalls or smooth clouds
• Videographers needing consistent shutter speed in changing light
• Portrait photographers using wide apertures outdoors
• Architectural and travel photographers controlling reflections and motion blur
