The K&F Concept VND2-32 CPL Filter KF01.2595 combines two useful lens filters in one compact design: a variable neutral density filter and a circular polarizer. Instead of carrying separate filters, photographers can control exposure and manage reflections with a single filter mounted on the lens.
The variable ND section provides 1 to 5 stops of light reduction, while the CPL function helps reduce unwanted reflections from non-metallic surfaces. It can also enhance contrast and make skies and foliage appear more saturated. As a result, the filter works well for both photography and video in changing lighting conditions.
2-in-1 VND and CPL Design
The main advantage of the KF01.2595 is its combination of two filters in one.
The variable ND function lets you control how much light reaches the camera sensor. Meanwhile, the CPL function manages reflections and can improve the appearance of skies, foliage, glass, and water.
This combination is particularly useful when you want to travel light without giving up exposure and reflection control.
1–5 Stops of Variable ND Control
The VND2-32 range provides approximately 1 to 5 stops of exposure reduction. This gives you more flexibility than a fixed ND filter because you can adjust the amount of light without removing the filter.
For video, this can help maintain a preferred shutter speed or aperture when shooting outdoors. For photography, stronger ND settings can allow longer exposures or wider apertures in bright conditions.
Therefore, the same filter can be useful across a variety of daylight situations.
Circular Polarizer for Reflection Control
The integrated CPL filter helps reduce reflections from non-metallic surfaces such as water and glass. It can also improve contrast and increase the visual intensity of blue skies and green foliage.
For landscape photography, this can make clouds and skies stand out more clearly. At the same time, reducing reflections from water can reveal more detail beneath the surface.
Multi-Coated Optical Glass
The KF01.2595 uses multi-coated optical glass to help maintain image clarity while reducing unwanted reflections. The coating also adds protection against everyday handling and helps make the filter easier to clean.
The filter is also listed with protective, nano, anti-static, and oil-resistant coatings, providing additional protection against dust, fingerprints, water stains, and other common contaminants.
Reduced Reflections and Improved Contrast
When you’re shooting outdoors, reflections can easily affect the final image. The CPL function helps manage these reflections while also improving contrast in suitable scenes.
For example, when photographing a lake, rotating the polarizer can reduce reflections on the water. Similarly, when shooting landscapes, the CPL effect can help make the sky and vegetation appear more defined.
Designed for Photography and Video
The K&F Concept KF01.2595 can be useful for both still photography and video production.
It works particularly well when you need to adjust exposure quickly without carrying a collection of individual ND filters. Because the CPL is built into the same filter, you can also control reflections without adding another filter to the front of the lens.
This makes the KF01.2595 a practical option for:
- Landscape photography
- Travel photography
- Outdoor photography
- Portrait photography
- Long-exposure photography
- Daylight video
- Cinematography
- Content creation
49mm Thread Size
The KF01.2595 uses a 49mm filter thread, so it is designed for lenses with a matching 49mm front thread.
Before purchasing, check the filter diameter printed on your lens. If your lens uses another size, you may be able to use a suitable step-up ring.
Practical Aluminum Construction
The filter uses an aluminum frame designed for everyday handling. One product listing specifies a frame thickness of approximately 9.3mm, giving the filter a solid construction while remaining compact enough for a camera bag.
The frame also uses a threaded mounting system, allowing the filter to screw directly onto a compatible lens.
