K&F CONCEPT 2-IN-1 CPL AND VARIABLE ND4-ND64 NANO-X SERIES 67MM FILTER

K&F CONCEPT 2-IN-1 CPL & VARIABLE ND4-ND64 NANO-X SERIES 67MM FILTER

The K&F Concept 2-in-1 CPL & Variable ND4-ND64 Nano-X Series 67mm Filter is a versatile professional camera filter that combines the creative benefits of a Circular Polarizer (CPL) and a Variable Neutral Density filter into one convenient optical accessory, giving photographers and videographers greater control over reflections, glare, colour saturation, contrast and exposure without constantly swapping between separate filters. Designed for lenses with a 67mm filter thread, the variable ND section provides an adjustable ND4-ND64 range, equivalent to approximately 2-6 stops of light reduction, allowing users to precisely control the amount of light entering the lens while maintaining their preferred aperture, shutter speed or ISO settings. This makes it particularly useful for video production, cinematic filmmaking, landscape photography, travel, automotive photography, waterfalls, moving water and outdoor portraiture, especially when working in bright daylight. At the same time, the integrated CPL function helps control polarised reflections from non-metallic surfaces such as water, glass, foliage and vehicle paintwork, while improving perceived colour saturation and contrast for richer, cleaner-looking images. Landscape photographers can use the polarising effect to deepen suitable blue skies, improve cloud definition, enhance foliage and reduce glare from water, while automotive and architectural photographers can gain greater control over distracting reflections. The adjustable ND function is equally valuable to filmmakers who want to maintain cinematic shutter speeds and wide apertures in bright conditions, as well as photographers who want to use slower shutter speeds to introduce intentional motion blur into waterfalls, rivers, clouds and other moving subjects. As part of K&F Concept's premium Nano-X Series, the filter is designed around high-quality optical performance and a durable, photography-focused construction, creating an excellent all-in-one solution for creators who would otherwise need to carry separate CPL and variable ND filters. By combining adjustable ND4-ND64 light control, circular polarisation and 67mm screw-in convenience in a single filter, the K&F Concept 2-in-1 CPL & Variable ND Nano-X Series Filter provides photographers and videographers with a highly practical tool for controlling challenging light and achieving creative effects directly in-camera.

Key Features:

• 2-in-1 CPL & Variable ND Filter – Combines a Circular Polarizer and Variable Neutral Density filter into one convenient accessory, reducing the need to continually switch between separate filters while shooting.

• 67mm Filter Thread – Designed for lenses featuring a 67mm front filter thread, making it suitable for a wide range of compatible DSLR and mirrorless camera lenses.

• ND4-ND64 Variable Neutral Density Range – Provides adjustable neutral density from ND4 through to ND64, giving photographers and filmmakers flexible exposure control as lighting conditions change.

• Approximately 2-6 Stops of Light Reduction – Allows the amount of light reaching the camera sensor to be reduced across an approximately 2-to-6-stop range.

• Variable Light Control – Instead of carrying several fixed-strength ND filters, users can adjust the filter density according to the scene and required exposure.

• Integrated Circular Polarizer – The built-in CPL provides control over polarised reflected light, helping photographers reduce unwanted glare and reflections from suitable non-metallic surfaces.

• Control Reflections from Water – The polarising function can reduce reflections from lakes, rivers, pools and other bodies of water, allowing greater control over whether surface reflections or detail beneath the water is emphasised.

• Reduce Reflections from Glass – Useful when photographing through suitable windows or glass surfaces where distracting reflections would otherwise interfere with the image.

• Control Automotive Reflections – Particularly useful for automotive photography, where a CPL can help manage reflections and glare across vehicle paintwork and windows.

• Enhance Foliage & Greenery – Reducing reflected glare from leaves can reveal more natural colour, saturation and texture in vegetation.

• Improve Landscape Colours – CPL functionality can increase perceived saturation and contrast by reducing unwanted reflected light from elements within an outdoor scene.

• Deepen Blue Skies – Under suitable lighting angles, polarisation can create a richer-looking blue sky and improve separation between the sky and clouds.

• Improve Cloud Definition – The polarising effect can help increase contrast between clouds and suitable areas of blue sky for more dramatic landscape photographs.

• Excellent for Landscape Photography – Combines two of the most useful outdoor filter functions, allowing photographers to manage reflections while simultaneously controlling exposure.

• Ideal for Waterfall Photography – ND light reduction allows slower shutter speeds to be used in brighter conditions, helping photographers create smooth, flowing motion effects in waterfalls.

• Great for Rivers & Moving Water – Provides additional exposure flexibility for intentionally blurring moving water while the CPL can simultaneously help control surface glare.

• Creative Long-Exposure Photography – Variable ND control makes it easier to extend shutter speeds in bright environments for creative movement effects in water, clouds and other moving subjects.

• Excellent for Outdoor Portrait Photography – Reducing incoming light can allow photographers to retain wider apertures in bright daylight rather than stopping the lens down purely to control exposure.

• Maintain Shallow Depth of Field – The ND function can help photographers and filmmakers continue using large apertures for stronger subject separation even under bright outdoor lighting.

• Ideal for Video Production – Variable ND filtration is particularly valuable for filmmakers who need to manage exposure without continually changing aperture, ISO or shutter speed.

• Maintain Cinematic Shutter Speeds – Reducing incoming light helps videographers maintain their desired shutter speed in bright conditions instead of being forced to use unnaturally fast shutter speeds simply to avoid overexposure.

• Excellent for Content Creators – Useful for outdoor video, travel filmmaking, social-media production, automotive content, product videos and other hybrid photo/video applications.

• Useful for Run-and-Gun Filmmaking – Adjustable density allows exposure to be changed as ambient lighting conditions vary without requiring a complete filter change.

• One Filter Instead of Two – Combining CPL and variable ND functions helps reduce the amount of equipment photographers and filmmakers need to carry.

• Reduces Filter Changes in the Field – Users can access polarisation and variable light reduction from the same filter rather than repeatedly removing and installing separate accessories.

• Excellent for Travel Photography – The multifunction design is particularly valuable when travelling because a single compact filter can perform several important photographic functions.

• Useful for Automotive Photography & Video – Combines reflection control with exposure management, making it particularly useful when capturing vehicles outdoors in bright conditions.

• Great for Architecture & Cityscapes – CPL functionality can help manage reflections from glass and other suitable surfaces, while the ND function provides greater exposure flexibility.

• Suitable for DSLR & Mirrorless Cameras – Compatibility is determined by the lens filter-thread diameter rather than the camera body, allowing the filter to be used across different camera systems when paired with a compatible 67mm lens.

• Check Your Lens Thread Before Ordering – Look for the Ø67mm marking on the front of the lens or underneath the lens cap to confirm direct compatibility.

• Screw-In Filter Design – Attaches directly to a compatible 67mm lens filter thread for a compact setup without requiring a separate filter holder.

• K&F Concept Nano-X Series – Part of K&F Concept's performance-focused Nano-X filter range, designed for photographers and videographers requiring dependable optical quality from their filters.

• Designed for High-Resolution Imaging – Nano-X Series construction is intended to complement modern high-resolution cameras while providing the creative advantages of optical filtration.

• Exposure Control Directly In-Camera – Neutral density filtration physically reduces the amount of light entering the lens, allowing exposure combinations that may otherwise be impossible under bright conditions.

• Optical Reflection Control – A CPL controls certain reflected light before it reaches the camera sensor, providing an effect that can be difficult or impossible to accurately reproduce solely through post-production.

• Greater Creative Control – Combining polarisation and neutral density gives photographers control over both the character of reflected light and the overall amount of light entering the camera.

• Ideal for Hybrid Shooters – Particularly useful for photographers who regularly switch between still photography and video because both CPL and variable ND functionality are available from one filter.

• Versatile Outdoor Photography Filter – Suitable for landscapes, travel, portraits, automotive, architecture, nature, waterfalls and other outdoor photography where reflections and bright ambient light need to be controlled.

• Practical All-in-One Filter Solution – The combined design provides a convenient alternative to carrying separate circular polarising and variable neutral density filters.
