K&F Concept Variable ND -suodatin ND8-ND2000 49mm

The K&F Concept Variable ND Filter ND8-ND2000 is a high-quality variable neutral density filter designed for photographers who need precise control over exposure in various lighting conditions. With a density range of ND8 to ND2000 (3 to 11 stops), this filter allows you to achieve long exposures, shallow depth of field, and smooth motion blur even in bright light. Crafted from Japanese AGC optical glass with a 28-layer multi-resistant coating, it ensures excellent image clarity, color neutrality, and durability. The ultra-slim frame (5.9mm) minimizes vignetting, making it ideal for wide-angle lenses. The filter also features a front thread for attaching a lens cap or stacking other filters.

Advantages

This variable ND filter offers versatility and convenience, eliminating the need to carry multiple fixed ND filters. The stepless adjustment from ND8 to ND2000 lets you quickly adapt to changing light. The advanced coating repels water, scratches, fingerprints, and reflections, ensuring clean images and easy maintenance. The aviation aluminum alloy frame is lightweight yet robust, and the design minimizes X-pattern artifacts at high densities.

Suitable for

• Landscape photography: Achieve silky waterfalls, smooth clouds, and motion blur.
• Portrait photography: Use wide apertures in bright conditions for shallow depth of field.
• Video recording: Maintain consistent shutter speed and aperture for cinematic motion blur.
• Architecture and travel: Reduce glare and control exposure in mixed lighting.
