The K&F Concept X Series VND8-128 KF01.1080 is an 82mm variable neutral density filter designed for photographers and videographers who need flexible exposure control without constantly changing filters. It provides a 3–7 stop light reduction range, allowing you to adjust the amount of light entering the lens by simply rotating the filter.
This makes the KF01.1080 particularly useful for outdoor photography, landscape work, and video production. For example, you can reduce bright daylight to maintain a wider aperture or use slower shutter speeds for creative motion effects. At the same time, the variable design keeps your setup compact because one filter covers several ND strengths.
3–7 Stops of Variable Light Reduction
The VND8-128 range provides between 3 and 7 stops of light reduction. This gives you considerably more control than a single fixed ND filter.
With the filter installed, you can adjust exposure while keeping other camera settings where you want them. This is especially useful for video, where maintaining a preferred shutter speed can help preserve consistent motion rendering.
For photography, the stronger ND settings can also help create smoother movement in scenes such as waterfalls, rivers, and other moving subjects.
No X Cross Effect
One of the main advantages of the K&F Concept KF01.1080 is its self-locking frame, which K&F Concept developed to minimize the common X-shaped cross effect associated with variable ND filters.
The frame provides a defined adjustment range, so you can move between the minimum and maximum settings without relying on an uncontrolled rotation.
As a result, the filter is particularly useful for videographers who need smooth and predictable exposure adjustments while recording.
AGC Optical Glass
The filter uses AGC optical glass, helping maintain image clarity and color performance while reducing incoming light. K&F Concept lists the glass as designed to preserve sharpness and minimize noticeable color cast.
This matters when working with detailed landscapes, high-resolution cameras, or video footage where unwanted color shifts can create extra work during editing.
Nano Coating for Everyday Protection
The KF01.1080 features multiple layers of nano coating designed to provide water resistance, scratch resistance, and anti-reflective performance. K&F Concept’s listings specify a multi-layer coating system on the optical surfaces.
Because of this, the filter is better suited to everyday outdoor shooting than an untreated glass filter. The coating also makes routine cleaning and handling more convenient.
Ultra-Slim 7.4mm Frame
The K&F Concept X Series VND8-128 uses an ultra-slim frame measuring approximately 7.4mm thick. The slim profile helps reduce the risk of vignetting, particularly when using wider lenses.
The frame also features a CNC-machined, non-slip design that makes the filter easier to install, remove, and rotate.
82mm Filter Size
The KF01.1080 is designed for 82mm lens filter threads. Before ordering, check the diameter symbol marked on your lens to confirm compatibility.
K&F Concept recommends using an 86mm lens cap with this filter because of the larger front structure.
If your lens uses a different filter thread, an appropriate step-up ring can provide another mounting option, provided the combination is compatible with your lens and setup.
Useful for Photography and Video
The K&F Concept KF01.1080 works particularly well when lighting conditions change quickly. Instead of carrying several fixed ND filters, you can adjust the filter to find the appropriate level of light reduction.
It is especially useful for:
- Landscape photography
- Outdoor photography
- Long-exposure photography
- Waterfall photography
- Video production
- Cinematography
- Travel photography
- Daylight shooting
For video creators, the variable adjustment can make it easier to control exposure while keeping aperture and shutter speed consistent.
