## Summary description

Two-in-one 52 mm hybrid photographic filter from K&F Concept combining a circular polarising (CPL) filter with a variable neutral density (ND4–ND64) filter. Designed for DSLR and mirrorless camera lenses with 52 mm thread, it reduces reflections and controls exposure range for long exposures, video and creative depth-of-field control. Useful for landscape, architecture and outdoor photography.

## Long description

Hybrid 2-in-1 52 mm Filter K&F Concept CPL Polariser + Variable ND4–ND64, model SB8070 is a combined optical accessory for DSLR and mirrorless camera lenses with a 52 mm filter thread. This hybrid filter integrates a circular polariser (CPL) and a variable neutral density (ND) element in a single 52 mm housing, allowing photographers and videographers to reduce surface reflections, deepen sky contrast and control exposure without changing filters. The variable ND range provides a continuous attenuation from about 2 to 6 stops, enabling long-exposure effects and wider-aperture shooting in bright conditions while the CPL improves color saturation and minimizes unwanted glare.
Advantages
The combined CPL and variable ND design simplifies workflow by eliminating the need to stack separate filters, reducing vignetting and keeping the lens front compact. The circular polariser works independently to rotate and adjust polarization for improved contrast and reduced reflections on water, glass and foliage. The ND section offers smoothly variable light reduction across its range for gradual control of exposure and motion blur. Constructed to fit lenses with a 52 mm thread, the filter maintains lens balance and preserves image quality when used correctly.
Suitable for
 Landscape photography to enhance sky contrast and manage exposure for long exposures
 Architectural and product photography to reduce reflections from glass and polished surfaces
 Outdoor portraiture and video when controlling depth of field and shutter speed in bright conditions
 Long-exposure creative effects such as smoothing water and motion blur
Key specifications
 Filter thread size: 52 mm compatible
 Filter type: combined circular polariser (CPL) and variable neutral density (ND)
 Variable ND range: approximately ND4 to ND64 (about 2 to 6 stops of light reduction)
 Construction: integrated two-in-one filter in a single slim mount
 Optical function: reduces reflections, increases color saturation, and controls exposure for long exposures and wide-aperture shooting
How to use
Attach the hybrid filter to any lens with a 52 mm front thread by screwing it onto the lens until it is snug but not overtightened. Rotate the CPL ring to adjust the amount of polarization until reflections and glare are reduced and sky contrast meets the intended look. Rotate the variable ND ring to dial in the desired light reduction; watch for exposure changes through the viewfinder or monitor and use a tripod for long-exposure work to avoid camera shake. When combining strong ND settings with wide-angle lenses, check for any darkening near frame corners and adjust composition or settings as needed.
Usage recommendations
Use the CPL function primarily when shooting at 90 degrees to the sun for maximum polarization effect, and start with lower ND values before increasing stops to avoid unwanted vignetting or color shifts. For long exposures, pair the filter with a stable tripod and remote release or self-timer. Store the filter in a protective case when not in use to prevent scratches and maintain optical performance.
