## Summary description

Hybrid 2-in-1 photographic lens filter by K&F Concept combining a circular polarizer (CPL) with a variable neutral density (ND) filter adjustable from ND2 to ND32. Designed for 55mm threaded lenses, it reduces reflections, enhances color saturation and contrast, and allows exposure control for longer shutter speeds or wider apertures in bright conditions. Suitable for landscape, architectural and long-exposure photography.

## Long description

The K&F Concept Hybrid 2-in-1 CPL + Variable ND2–ND32 55mm is a combined photographic filter that integrates a circular polarizer (CPL) with an adjustable neutral density (ND) element for lenses with a 55mm front thread. This hybrid filter reduces surface reflections and glare, improves color saturation and contrast, and lets photographers control exposure by varying light transmission from approximately one to five stops. The compact design replaces the need to stack separate CPL and ND filters and maintains a low profile suitable for wide-angle and standard lenses with 55mm threads.
Advantages
The integrated CPL function removes unwanted reflections from non-metallic surfaces such as water and glass while increasing sky and foliage color definition. The variable ND component allows smooth adjustment between ND2 and ND32 to extend shutter speeds or enable wider apertures in bright conditions without changing exposure settings. Combining both functions in a single 55mm threaded unit reduces vignetting risk compared with stacked filters, simplifies handling on the lens, and speeds up composition adjustments in the field.
Suitable for
 Landscape photography requiring enhanced skies and controlled reflections
 Architectural photography where glass and reflective surfaces are present
 Long-exposure effects for water, clouds, and motion blur in daylight
 Portraits and shallow-depth-of-field shots in bright conditions where wider apertures are needed
Key specifications
 Filter type: Combined circular polarizer (CPL) and variable neutral density (ND)
 ND range: adjustable from approximately ND2 to ND32 (about 1 to 5 stops of light reduction)
 Mount thread size: 55 mm
 Optical design: slim profile to minimize vignetting on wide-angle lenses
 Finish: multi-coated glass surfaces to reduce flare and ghosting
How to use
Mount the filter on a lens with a 55mm front thread by screwing it in until snug; avoid over-tightening. Rotate the front element to engage the CPL function and observe the effect on reflections and sky saturation through the viewfinder or live view. Rotate the inner/outer ring (depending on the filter construction) to vary the ND density until the desired exposure or motion blur is achieved. When using long exposures, use a stable tripod and, where available, a remote shutter release or camera timer to prevent camera shake.
Usage recommendations
Check for cross-polarization effects when shooting through some types of glass or LCD screens; adjust rotation to minimize unwanted banding. For ultra-wide-angle lenses, monitor for vignetting at stronger ND settings and consider stopping down the aperture or using a dedicated full-frame ND if heavy light reduction is required. Clean the filter surfaces with a soft microfiber cloth and appropriate lens cleaner to maintain optical performance.
