Choosing a circular neutral density (ND) filter helps photographers and videographers control light intake, enabling longer exposure times and richer motion in scenes from waterfalls to city light trails. The following hand-picked filters combine ND and CPL functionality in a single unit, with robust coatings and high-quality glass to preserve color and detail. This guide highlights five strong options across common lens sizes, plus a practical buying guide to help you compare features like stops, coatings, and cross-free performance.

K&F CONCEPT 82mm True Color Variable Fader ND2-32 ND Filter and CPL
This 82 mm K&F CONCEPT filter combines a variable ND and CPL in a single unit, allowing precise light reduction (ND2-32) and polarizing control to minimize reflections from water, glass, and other non-metallic surfaces. The filter aims to preserve color while delivering higher contrast and deeper skies. It uses imported AGC optical glass with multiple coatings for durability and water resistance. The self-locking frame supports smooth rotation and infinite stops, helping avoid cross-pattern issues that can occur with some variable ND designs.
K&F CONCEPT 67mm Variable Fader ND2-32 ND Filter and CPL
This 67 mm option offers ND and CPL in one unit with the same self-locking mechanism to prevent X-cross artifacts. The ND range (1–5 stops) enables nuanced exposure control for landscapes and water scenes, while the CPL helps reduce glare and enhance color contrast. AGC optical glass with multi-layer coatings is designed for waterproof performance and high-definition results, helping maintain accurate color rendition across scenes.
K&F CONCEPT 82mm Variable ND2-ND400 ND Lens Filter (B-Series)
This 82 mm filter provides 1–9 stops of light reduction with 360-degree rotation for smooth, precise dimming. The ND range covers a wide spectrum of lighting conditions, making it suitable for rivers, waterfalls, long exposure cityscapes, and motion-blurred imagery. The filter’s surface is treated to minimize stray light and unwanted reflections, helping keep image clarity even at higher stops. Note: Extreme stops may cause cross patterns with certain lenses, a common trait with multi-stop ND designs.
K&F CONCEPT 55mm Variable Fader ND2-32 ND Filter and CPL
This 55 mm unit combines a variable ND with a CPL in one compact filter, targeting smaller lenses or compact setups. It includes self-locking design to minimize X-crossing while offering 1–5 stops of light reduction. The imported AGC optical glass with multi-layer coatings is designed to preserve color fidelity and reduce reflections, ensuring sharp, vibrant output across a range of exposures and environments.
NEEWER 72mm Variable ND Filter ND2-ND400
NEEWER’s 72 mm variable ND filter features a 1–9 stop range with a robust multi-coating system. Built from high-quality glass and designed to minimize flare and ghosting, this filter is suitable for landscapes, rivers, and city scenes with changing light. The product emphasizes both UV protection and color neutrality, helping to maintain natural tones while enabling longer exposure times at wider apertures.
K&F CONCEPT 58mm Variable Fader ND2-32 ND Filter and CPL
This 58 mm option provides the same dual ND and CPL capabilities with a self-locking frame that avoids X-cross artifacts. The 1–5 stop range suits mid-day scenes and waterfronts, while AGC optical glass and 24-layer coatings help maintain image clarity, color accuracy, and resistance to moisture and dust, supporting reliable performance in varied conditions.
Buying Guide: Key Purchase Considerations
When selecting a circular ND filter, consider the following perspectives to ensure the best match for your gear and shooting style:
- Stop Range and Type: Decide between fixed ND values (e.g., ND2-ND400) and variable ND that spans multiple stops. Variable ND offers flexibility but can introduce color shifts or X-crossing at extreme stops, depending on the lens and design.
- Lens Size Compatibility: Choose the filter diameter that matches your main lenses, or carry step-up rings for flexibility. Common sizes include 58 mm, 67 mm, 82 mm, and 72 mm among the options listed.
- Integrated CPL Benefit: Filters that combine ND and CPL save space and time, helping reduce glare while controlling exposure. Test color accuracy with and without CPL in your typical scenes.
- Glass Quality and Coatings: Look for high-quality optical glass (e.g., AGC) with multi-layer coatings to reduce reflections, flare, and scratches. Coatings also aid in water and oil resistance for outdoor shoots.
- Cross-Pattern Risk: Some variable ND designs may produce a cross (the “X” pattern) at higher stops with specific lens combos. If you shoot long exposures at strong stops, choose designs explicitly noting anti-cross features.
- Durability and Mounting: Self-locking frames or sturdy mechanical builds help maintain alignment during rotation and reduce wear on the filter ring.
- Maintenance: Cleaning cloths and microfiber care are recommended, especially when using on water or outdoor scenes with dust and moisture.
In practice, the best choice depends on your typical focal lengths, desired exposure control, and whether you prefer combination ND/CPL filters for streamlined kits. The five products highlighted above cover common sizes and include both single-brand consistency and cross-compatibility across popular lens diameters.
