K&F CONCEPT VARIABLE ND2-400 HMC 58MM FILTER

K&F CONCEPT VARIABLE ND2-400 HMC 58MM FILTER

The K&F Concept Variable ND2–400 HMC 58mm Filter is a precision-engineered variable neutral density filter designed for photographers and videographers who require absolute control over exposure, motion, and depth of field in any lighting environment. With a versatile ND range equivalent to 1–8 f-stops, this filter allows you to smoothly adjust light entering your lens—perfect for long-exposure landscapes, cinematic video, wide-aperture portraits, and bright outdoor scenes. Built from premium Japanese optical glass with advanced 18-layer multi-coatings, the ND2–400 delivers exceptional clarity, eliminates color cast, and minimizes reflections for the highest image quality. Its ultra-slim, aircraft-grade aluminium frame prevents vignetting even on wide-angle lenses, while the waterproof, scratch-resistant, and oil-repellent nano-coating ensures durability on location. Whether you're capturing silky waterfalls, dreamy motion blur, or bright daylight video with perfect shutter control, this versatile variable ND filter is an essential tool for elevating creative results without the need to carry multiple fixed ND filters.

Key Features

• Adjustable ND2–400 Light Reduction (1–8 Stops)
  Seamlessly rotate the filter ring to control exposure levels, enabling smooth long exposures, bright-light shooting, and shallow depth-of-field effects without overexposure.

• Professional Exposure Control for Photo & Video
  Helps maintain ideal shutter speeds for cinematic 24/30/60fps video and enables creative long-exposure effects like waterfalls, cloud streaks, and motion blur.

• Premium Japanese Optical Glass Construction
  Double-polished, high-transparency glass ensures ultra-sharp image detail, accurate color rendering, and professional-grade clarity even on high-resolution cameras.

• 18-Layer Multi-Coating System
  Reduces lens flare, ghosting, and unwanted reflections while increasing light transmittance for stunning contrast, clean highlights, and improved overall image quality.

• Waterproof, Oil-Resistant & Scratch-Proof Nano Coating
  Blue nano-layer coating resists fingerprints, dust, smudges, rain, and abrasion—ideal for outdoor, travel, or landscape photographers who shoot in demanding environments.

• Ultra-Slim 3mm Aluminium Frame Design
  Durable, lightweight aircraft-grade aluminium minimizes vignetting and ensures smooth rotation while maintaining structural strength and long-lasting performance.

• Stepless Smooth Rotation Ring
  Provides precise control over density adjustments with clearly marked index points for consistent and repeatable exposure settings.

• Eliminates the Need for Multiple ND Filters
  One variable filter replaces numerous fixed ND filters, reducing weight in your camera bag and simplifying fast-paced shoots.

• Wide-Angle Compatibility with Anti-Vignetting Engineering
  Oversized optical surface ensures edge-to-edge clarity and prevents dark corners, even when used with 58mm wide-angle lenses.

• Double-Threaded for Filter Stacking
  Allows attachment of additional filters such as CPL or UV on top, expanding creative control for both photography and videography.
