K&F Hybrid CPL + Variable ND2–ND32 Camera Lens Filter 77mm (SB6225)

The K&F Hybrid CPL + Variable ND2–ND32 Camera Lens Filter 77mm combines a circular polarizer and an adjustable neutral density filter into a single 77mm unit. It reduces reflections from non-metallic surfaces and increases color saturation and contrast while offering variable light attenuation from approximately 1 to 5 stops (ND2–ND32). The integrated design saves time and front filter threads compared with using separate CPL and ND filters, making it practical for landscape, architecture and motion-blur photography where control of reflections and exposure is required.

Advantages

This hybrid filter provides the benefits of both a CPL and a variable ND in one compact accessory: reflection suppression for clearer skies and foliage, enhanced color saturation and contrast, and continuously adjustable light reduction for longer exposures or wider apertures. Its 77mm diameter fits lenses with that thread size, and the combined mechanism simplifies workflow by allowing polarization rotation and density adjustment without changing filters. The construction is intended to maintain image sharpness and minimize vignetting when used within the filter’s intended range.

Suitable for

• Landscape photography to manage glare and deepen sky color
• Architectural photography to reduce window and surface reflections
• Motion blur and long-exposure photography in daylight
• Outdoor portraiture when controlling shallow depth-of-field in bright conditions

Key specifications

• Filter type: combined circular polarizer (CPL) and variable neutral density (ND2–ND32)
• Thread size: 77 mm
• Variable density range: approximately 1 to 5 stops (ND2 to ND32)
• Functionality: adjustable polarization and continuous light attenuation
• Primary effects: reflection reduction, increased color saturation, contrast enhancement, controlled exposure

How to use

Attach the filter to a lens with a 77mm front thread and secure it by turning until seated. Rotate the polarizer element to reduce reflections and adjust polarization effect; then rotate the outer ring to set the desired ND density for exposure control. Check your camera’s exposure meter and preview the image to confirm the combined effect. When using stronger ND settings, use a tripod and remote release or mirror lockup for stable long exposures. If using autofocus, verify focus before applying heavy ND settings and consider manual focus if necessary.

Usage recommendations

Avoid stacking additional density filters on top of the hybrid filter to prevent excessive vignetting and image degradation. For best results in high-contrast scenes, combine modest ND settings with graduated exposure or bracketing techniques. Clean filter surfaces with a microfiber cloth and appropriate lens-cleaning solution to maintain image quality.
