Kase 2-in-1 Variable ND & CPL Filter - Stepless Light Control for Video and Photography

Elevate your visual storytelling with the Kase Variable ND-CPL 2-in-1 filter. Designed specifically for professional videographers and portrait photographers, this versatile tool combines the light-reducing power of a Neutral Density (ND) filter with the glare-cutting capabilities of a Circular Polarizer (CPL). Whether you are shooting high-frame-rate video in bright sunlight or capturing outdoor portraits with a wide aperture, this filter provides the precision control you need to master exposure and color saturation in a single, compact unit.

Key Benefits

Dual-Function Integration:** Seamlessly combines a variable ND and a CPL filter into one frame. This hybrid design reduces the need to stack multiple filters, which helps prevent vignetting and maintains a slim profile on your lens.

Stepless Light Adjustment:** Features a smooth, stepless adjustment mechanism that allows you to dial in the exact amount of light reduction required for perfect exposure. It offers a versatile range of stops to handle various lighting environments.

Reflection & Glare Suppression:** The integrated CPL effectively eliminates unwanted reflections from non-metallic surfaces like water, foliage, and glass, while simultaneously enhancing color depth and sky contrast.

Professional Video Optimization:** An essential tool for "one-lens" shooting scenarios, enabling you to maintain a consistent shutter speed for cinematic motion blur even as ambient lighting conditions shift.

Stable Exposure Control:** Engineered to help photographers achieve accurate exposure effortlessly, ensuring that your highlights remain protected and your shadows retain detail in high-contrast scenes.

Key Specs

Filter Type:** Variable Neutral Density (ND) + Circular Polarizer (CPL) 2-in-1.

Adjustment Range:** Multi-stop stepless control (including 2-stop and 5-stop benchmarks).

Application:** Portrait photography, outdoor videography, and landscape shooting.

Primary Function:** Exposure management and non-metallic reflection suppression.

How to Use

1. **Attachment:** Carefully screw the filter onto the front thread of your camera lens until it is securely seated.

2. **Adjusting Light (ND):** Rotate the designated adjustment ring to increase or decrease the light density. This allows you to use wider apertures or slower shutter speeds in bright conditions.

3. **Controlling Reflections (CPL):** Rotate the polarization ring while looking through the viewfinder or at your LCD screen. Stop when the glare on your subject (such as a window or water surface) is minimized.

4. **Seamless Transitions:** For video work, you can adjust the density on the fly to maintain a "one-shot" flow when moving between different lighting zones.

Care & Safety

Storage:** Always store the filter in a dedicated protective case when not in use to prevent scratches, impact damage, and dust accumulation.

Cleaning:** Use a professional lens blower or a clean microfiber cloth to remove debris. Avoid using abrasive materials or harsh household chemicals that could strip the specialized optical coatings.

Handling:** Grip the filter by the metal edges to avoid leaving fingerprints or oils on the glass surfaces.

Notes

"One lens for different scenes, directly adjust the light reduction on the filter for total convenience."
