K&F CONCEPT VARIABLE ND2-400 HMC 52MM FILTER

K&F CONCEPT VARIABLE ND2-400 HMC 52MM FILTER

The K&F Concept Variable ND2–400 HMC 52mm Filter is an essential creative tool for photographers and videographers who demand full control over light, exposure, and artistic expression in any environment. Engineered with premium Japanese optical glass, multi-layer coatings, and an ultra-slim aluminium frame, this variable ND filter delivers seamless 1–8 f-stops of light reduction—allowing you to extend shutter speeds, achieve cinematic motion blur, shoot wide-open apertures for shallow depth of field, and maintain perfect exposure even under harsh sunlight. Acting like fully adjustable sunglasses for your lens, the ND2–400 transforms any bright outdoor scene into a controlled creative canvas, enabling landscape shooters, portrait photographers, travel creators, and filmmakers to produce stunning, high-fidelity images with deeper contrast, smoother motion, and professional-grade color accuracy. With durable construction, waterproof/scratch-resistant coatings, smooth rotating action, and a double-threaded mount for stacking, this filter delivers exceptional performance in a compact, travel-friendly design—making it the most versatile ND solution you can carry.

Key Features:

• 1–8 f-Stops Variable Light Reduction – Seamlessly adjust exposure by rotating the filter, offering precise control from ND2 to ND400 for long exposures, motion blur, shallow depth of field, and balanced daylight shooting.

• Creative Exposure Control for Photography & Video – Extend shutter speeds to create cloud streaks, silky water, and dynamic motion blur; open your aperture wide for portrait separation; and manage exposure easily during filmmaking where shutter speed must remain fixed for cinematic motion.

• Premium Japanese High-Precision Optical Glass – Double-sided polished optics deliver ultra-high-definition results up to 8K resolution, ensuring clarity, accurate color, and minimal distortion across the entire frame.

• Advanced Multi-Layer Coating System – Includes 18 layers of anti-reflection coating to minimize flare and ghosting, enhance light transmittance, and maintain clean contrast even in harsh lighting conditions.

• Waterproof, Scratch-Resistant Blue Nano-Coating – Repels water, oil, fingerprints, and dust while protecting the glass surface from abrasion—ideal for outdoor, travel, and landscape shooting.

• Ultra-Slim 3mm Aircraft-Grade Aluminium Frame – Lightweight, durable, and precisely machined to reduce vignetting on wide-angle lenses; double-threaded for stacking additional filters when needed.

• Smooth, Stepless Rotation Mechanism – Textured grip and fluid ring movement allow intuitive exposure adjustment without hard stops, supported by dot and arrow calibration marks for repeatable results.

• Eliminates the Need for Multiple ND Filters – One adjustable ND replaces several fixed-density filters, saving space, reducing gear weight, and eliminating time wasted swapping filters in the field.

• Enhanced Video Performance – Works as a manual exposure control tool for videographers, enabling consistent shutter speeds and cinematic results without relying on camera body settings.

• Minimised Vignetting & Neutral Color Rendering – Oversized glass and precision alignment reduce dark corners and color shifting—common issues with cheaper ND filters.

• Secure Fit & Simple Operation – Textured aluminium frame provides a confident grip for attaching, removing, and rotating the filter safely even in wet or dusty environments.

• Includes Protective Carry Case – Hard plastic case shields the filter from scratches, dust, and impact during transport, keeping your optical gear safe and ready for action.
