K&F Concept 52mm 3-in-1 Hybrid Filter: Variable ND2-32, CPL, Black Diffusion 1/4 (KF01.2063)

The K&F Concept 52mm 3-in-1 Hybrid Filter combines a Variable Neutral Density (ND2-ND32), Circular Polarizer (CPL), and Black Diffusion 1/4 filter into a single, versatile accessory. Designed for photographers and videographers, this filter allows precise control over exposure, reflections, and soft focus effects without the need to swap filters. The high-definition optical glass with multi-layer nano coating ensures sharp, clear images while providing water, oil, and scratch resistance. The aviation aluminum alloy frame is lightweight yet durable, making it an ideal companion for on-the-go shooting.

Advantages

This 3-in-1 design saves time and space in your camera bag, enabling quick adjustments to lighting conditions and creative effects. The variable ND range (1-5 stops) lets you achieve long exposures or shallow depth of field in bright light, while the CPL reduces glare and enhances color saturation. The Black Diffusion 1/4 adds a subtle soft focus effect, perfect for portraits or dreamy landscapes. All functions are controlled by rotating the filter ring, offering seamless transitions.

Suitable for

• Landscape photography with long exposures
• Portrait photography with soft focus effects
• Videography requiring variable ND for smooth exposure
• Outdoor shooting with reflective surfaces (water, glass)
• Travel and street photography where versatility is key
