Photography is all about light — how much of it enters your lens and how creatively you use it. Whether you’re shooting in bright midday sun, working with moving water, or capturing cinematic video, a variable ND filter can be your best friend. At Kenko Tokina, we design optical tools that help you control light with precision, and our camera lens filters are trusted for quality and performance.
What Is a Variable ND Filter?
A variable ND filter (Neutral Density) is an adjustable optical filter that reduces the amount of light entering your lens without changing color. Unlike fixed ND options that require multiple strengths, a variable ND lets you dial in the exact density by rotating the ring. One tool, many levels of control — perfect for photographers and filmmakers.
Why Use a Variable ND Filter?
- Control Bright Scenes: Keep wide apertures for shallow depth of field in daylight without overexposing.
- Create Motion Blur: Use slower shutter speeds to smooth waterfalls, soften seas, and paint light trails.
- Cinematic Video: Maintain the 180° shutter rule in sunlit scenes for natural motion blur.
- Fast Adjustments: Twist to the right density instead of swapping multiple filters.
Variable ND Filter vs. Other Camera Lens Filters
Kenko Tokina offers a complete lineup of camera lens filters, each built for a specific job:
- UV Filters: Everyday protection against dust, scratches, and UV light.
- Polarizers: Reduce reflections, deepen skies, and boost color saturation.
- Fixed ND: Consistent density; great when you know the exact stop you need.
- Variable ND Filter: Flexible control across multiple ND strengths in a single filter.
Pairing these with high‑grade glass and coatings means sharper images, minimal color shift, and reliable durability — the hallmarks of Kenko Tokina.
How to Choose the Right Variable ND Filter
