## Summary description

Hybrid 2‑in‑1 camera filter by K&F Concept combining circular polarizer (CPL) and variable neutral density (ND2–ND32) in a single 52 mm screw‑mount unit. Provides glare and reflection reduction, enhanced color saturation from the CPL and adjustable light attenuation from ND2 to ND32 for longer exposures, video aperture control, and depth‑of‑field management. Suited for landscape, architecture, and outdoor photography and videography where both polarization and variable density are required without changing filters.

## Long description

The K&F Concept Hybrid camera filter CPL + variable ND2–ND32 for 52 mm lenses is a compact 2-in-1 optical accessory that combines a circular polarizer with an adjustable neutral density element in a single screw-mount unit. Designed for 52 mm filter-thread lenses, this hybrid filter reduces surface glare and reflections while allowing continuous control of light transmission between approximately 1 and 5 stops (ND2–ND32). It enables improved color saturation and contrast from the CPL function together with variable exposure control useful for longer shutter speeds, controlled aperture for video and balanced depth-of-field in bright conditions.
Advantages
This combination filter saves time and reduces the need to carry multiple separate filters by integrating polarization and variable neutral density in one lightweight housing. The circular polarizer layer improves color rendering and cuts reflections from non-metallic surfaces, while the variable ND ring provides smooth attenuation across its range for gradual exposure adjustments. The screw-mount design ensures secure attachment to 52 mm lenses and maintains optical alignment without extra adapters. Materials and coatings are selected to minimise flare and ghosting, supporting clearer results for outdoor and on-location shoots.
Suitable for
Landscape photography to deepen skies and control highlights
Architectural photography to reduce window and facade reflections
Outdoor portraiture to manage background blur and exposure in bright light
Video production for aperture and exposure control without changing neutral density filters
Long-exposure effects such as smoothing water and motion blur in daylight
Key specifications
Filter type: hybrid circular polarizer (CPL) + variable neutral density (ND2–ND32)
Mount thread: 52 mm screw-in
Variable density range: ND2 up to ND32 (approx. 1–5 stops of light reduction)
Polarizer: circular design for compatibility with modern autofocus and metering systems
Construction: multi-element optical glass with anti-reflective coatings
Finish: low-profile metal frame to reduce vignetting on wide-angle lenses
How to use
Attach the filter to a lens with a 52 mm thread by screwing it into place until secure. Rotate the polarizer element while observing reflections or sky through the viewfinder or live view to find the desired polarization effect. Then, turn the variable ND ring to achieve the required exposure reduction; watch the exposure indicator or histogram to confirm correct light levels. For video work, adjust the ND ring to maintain desired aperture and shutter settings without changing lenses or stopping down. When stacking other accessories, check for vignetting on wide-angle focal lengths.
Usage recommendations
For best results, set polarization before dialing in the ND strength. Use live view or an electronic viewfinder to assess the combined effect of polarization and density, and avoid extreme ND settings when shooting through deep shadows where color shifts may occur. Clean the filter surfaces with a soft, lint-free cloth and store it in a protective case when not in use to preserve coatings and optical performance.
