Fits lenses with 77 mm filter thread for landscape, architecture, and long‑exposure photography.

## Long description

The Hybrid Filter K&F Concept 2-in-1 CPL + Variable ND2–ND32 for 77 mm lenses combines a circular polarizer and an adjustable neutral density filter in a single 77 mm screw-in unit. This compact photographic accessory provides polarization control to reduce reflections on non-metallic surfaces and to increase color saturation, while an integrated variable ND element offers continuous light reduction from approximately 1 to 5 stops (ND2–ND32). The filter is designed to fit lenses with a 77 mm filter thread and is suitable for landscape, architecture, and long-exposure photography where both reflection control and exposure reduction are required.
Advantages
The combined CPL and variable ND functionality eliminates the need to carry separate filters, saving space on the camera bag and simplifying filter changes in the field. The circular polarizer element helps cut glare from water, glass, and foliage and improves sky contrast. The variable ND range allows flexible control of exposure and depth of field, enabling longer shutter speeds or wider apertures under bright conditions. The one-piece 77 mm design screws onto compatible lenses for secure attachment and quick operation.
Suitable for
Landscape photography to enhance sky contrast and color saturation
Architecture and urban scenes to reduce reflections on windows and surfaces
Long-exposure photography of water, clouds, and moving subjects
Portraits and outdoor shooting when wider apertures are required in bright light
Key specifications
Filter type: Circular polarizer (CPL) combined with variable neutral density (ND2–ND32)
Thread size: 77 mm screw-in mount
ND range: approximately 1 to 5 stops (variable ND2 to ND32)
Polarizer: circular design for use with modern autofocus and exposure metering systems
Material: multi-coated optical glass elements with metal filter ring
How to use
Screw the filter onto the front of a lens with a 77 mm filter thread until hand-tight. Rotate the outer ring to adjust the circular polarizer effect and observe changes in reflections and color saturation through the viewfinder or live view. To change light reduction, turn the variable ND ring and monitor exposure settings, shutter speed, or aperture; use a light meter or camera histogram for precise control. When combining CPL and ND adjustments, make incremental rotations to avoid abrupt exposure changes and check for vignetting at wide focal lengths. Remove the filter and store it in its protective case when not in use.
Usage recommendations
For best results, set white balance or use RAW capture to preserve color accuracy, and verify focus after applying heavy ND settings since autofocus performance can be affected. When shooting at extremes of the variable ND range, inspect images for uneven darkening or cross-polarization effects and adjust rotation slightly to minimize these artifacts.
