Camera Filter K&F Concept Hybrid 2-in-1 CPL Polarizer + Grey ND2–ND32 Fader 82mm

The Camera Filter K&F Concept Hybrid 2-in-1 CPL Polarizer + Grey ND2–ND32 Fader 82mm combines a circular polarizer and an adjustable neutral density filter in a single 82mm optical element. The circular polarizer reduces reflections from non-metallic surfaces and increases color saturation, while the variable ND fader provides continuously adjustable light reduction equivalent to approximately 1 to 5 stops. Built to fit lenses with an 82mm filter thread, this hybrid filter supports exposure control and contrast management without the need to carry separate CPL and ND filters.

Advantages

This hybrid design streamlines gear by integrating polarizing and variable density functions into one 82mm unit, simplifying filter changes in the field. The circular polarizer component improves sky contrast and reduces unwanted glare from water and glass. The variable ND range from ND2 to ND32 allows gradual control of shutter speed and aperture for motion blur, shallow depth-of-field in bright light, and balanced exposures in high-contrast scenes. The threaded mount maintains compatibility with standard 82mm lenses and permits stacking with other compatible accessories when required.

Suitable for

• Landscape photography to enhance skies, foliage color, and reduce reflections
• Long-exposure scenes such as waterfalls, rivers, and clouds where variable light reduction is needed
• Outdoor portraiture when controlling depth of field and minimizing glare from faces and surroundings
• Architectural and product photography to reduce window and surface reflections

Key specifications

• Filter type: Hybrid circular polarizer + variable neutral density (ND2–ND32)
• Thread diameter: 82 mm
• Variable ND range: approximately 1 to 5 stops of light reduction
• Polarizer type: Circular polarizer for compatibility with auto-exposure and autofocus systems
• Construction: Multi-component optical element with rotating polarizer and adjustable density control

How to use

Attach the filter to any lens with an 82mm front thread and secure it by gently threading until snug; avoid overtightening. Rotate the polarizer element while viewing the scene through the viewfinder or live view to reduce reflections and adjust color saturation to the desired level. Use the variable ND control to dial in the appropriate amount of light reduction for the intended shutter speed or aperture. When combining polarizer and ND adjustments, make incremental changes and monitor exposure and histogram to avoid under- or overexposure. If long exposures are planned, use a sturdy tripod and remote release or timer to prevent camera shake.

Usage recommendations

For best results on bright days, set the polarizer first to manage reflections and color, then adjust the ND fader to achieve the target shutter speed or aperture. Beware of potential cross-polarization effects at wide angles when using very strong polarization together with the ND setting; slightly change camera angle or reduce polarization rotation if uneven darkening of the sky appears. Store the filter in a protective case when not in use to preserve optical coatings and threads.
