## Summary description

Hybrid 2-in-1 camera filter by K&F combining a circular polarizer (CPL) with a variable neutral density (ND) fader covering ND2 to ND32. Thread size 49 mm. Designed to reduce reflections, enhance color saturation, and control exposure for longer shutter speeds or wider apertures. Suitable for landscape, architecture, and portrait photography where glare reduction and adjustable light attenuation are needed.

## Long description

The K&F Hybrid Camera Filter 2-in-1 CPL Polarizer + Variable ND2–ND32 Fader 49 mm combines a circular polarizer and an adjustable neutral density filter in a single 49 mm threaded unit. This hybrid filter is designed to reduce surface reflections, increase color saturation, and provide variable light attenuation from approximately 1 to 5 stops, enabling longer exposures or wider apertures without changing lenses. The compact, screw-on design fits lenses with a 49 mm filter thread and is suitable for photographers who want both polarization control and flexible ND adjustment in one accessory.
Advantages
The integrated CPL element removes glare from non-metallic surfaces and improves sky contrast and color depth, while the variable ND fader offers smooth control over exposure without the need to swap fixed ND filters. The single-piece construction saves space in the kit and reduces the need to carry multiple filters. Precision-threaded metal mounts ensure stable attachment and alignment, and the optical glass surfaces are treated to maintain image sharpness and minimize unwanted color cast.
Suitable for
 Landscape photography — enhancing skies and controlling reflections on water and foliage
 Architecture and exterior shoots — reducing window and facade glare
 Portraits in bright light — enabling wider apertures for shallow depth of field
 Long exposure effects — creating motion blur in water or clouds with variable attenuation
Key specifications
 Filter type: Circular polarizer combined with variable neutral density
 Variable ND range: ND2 to ND32 (approx. 1 to 5 stops of attenuation)
 Thread size: 49 mm screw-in mount
 Construction: Multi-element optical glass with metal filter ring
 Control: Rotating front ring for CPL and separate rotation for ND adjustment within the single assembly
How to use
Screw the filter onto the lens front threads (49 mm). First rotate the CPL element to set the desired polarization effect by observing reflections and sky contrast through the viewfinder or live view. Then rotate the ND control to adjust the amount of light reduction until the exposure and shutter speed are appropriate for the creative result you want. Check for any vignetting at wide focal lengths and use mirrorless or DSLR exposure preview to confirm settings. When stacking other filters, be aware of potential cross-polarization or increased risk of vignetting.
Usage recommendations
Use the CPL when shooting at angles 30–90° to the sun for best polarization effect; avoid extreme ND settings that cause uneven darkening at wide-angle focal lengths. Clean optical surfaces with a microfiber cloth and store the filter in its case when not in use to preserve coatings and alignment.
