Hybrid Camera Filter K&F Concept 2-in-1 CPL + Solid Neutral Density ND2–ND32 for 58 mm lenses

The K&F Concept Hybrid Camera Filter 2-in-1 CPL + Solid Neutral Density ND2–ND32 for 58 mm lenses combines a circular polarizer and a range of solid neutral density filters in a single 58 mm optical unit. This integrated design gives photographers polarization control to reduce reflections and deepen sky tones while also offering fixed-step light reduction from ND2 up to ND32 to enable longer exposures or wider apertures. The filter is intended for use on 58 mm threaded lenses and is suitable for landscape, architecture and outdoor photography where control of glare, contrast and exposure is required.

Advantages

The hybrid construction merges two common optical tools into one element, reducing the need to carry and swap multiple filters. The circular polarizer component minimizes reflections from non-metallic surfaces and increases color saturation and sky contrast, while the solid neutral density range provides consistent light attenuation across the ND2–ND32 steps to extend exposure times or allow larger aperture settings. The 58 mm threaded format ensures compatibility with lenses that use that filter size and simplifies attachment and removal during shoots.

Suitable for

• Landscape photography to deepen skies and control exposure during daytime long exposures
• Architectural and urban photography to reduce window and facade reflections
• Outdoor portraiture when a wider aperture is needed in bright light
• Long-exposure water and cloud motion effects
• General outdoor shooting where polarization and stepped neutral density are both useful

Key specifications

• Filter type: Hybrid 2-in-1 combining circular polarizer (CPL) and solid neutral density (ND2–ND32)
• Filter thread size: 58 mm
• ND range: fixed-step light reduction from ND2 to ND32
• Optical construction: multi-coated glass elements to reduce reflections and maintain color fidelity
• Mount: screw-in metal frame compatible with 58 mm lens threads

How to use

Screw the filter onto the front of a lens with a 58 mm thread until it is secure but not overtightened. Rotate the CPL element to adjust the degree of polarization while observing reflections and sky contrast in the viewfinder or live view. Select the desired ND step according to the required exposure reduction; the solid ND portion provides defined stops between ND2 and ND32. Combine the CPL rotation with the chosen ND setting to balance glare reduction and exposure control. Check exposure on the camera and adjust shutter speed, aperture, or ISO as needed when using ND attenuation for longer exposures.

Usage recommendations

Use the CPL function at roughly a 90-degree angle to the sun for maximum polarization effect. When using stronger ND settings, employ a tripod and mirror-lockup or electronic shutter features to avoid camera shake. Clean both sides of the filter before attaching and store the filter in a protective case when not in use to preserve coatings and optical performance.
