## Summary description

The K&F Concept Nano-X Variable Neutral Density Filter (37 mm) allows for precise control of light entering the lens, enhancing your photography by enabling longer exposures and wider apertures in bright conditions. Its high-quality optical glass ensures minimal color cast and distortion, while the durable black finish reduces reflections. Ideal for landscape and portrait photography, this filter is a must-have for creative photographers.

## Long description

ND filters (neutral density) reduce the amount of light entering the lens, making it easier to use longer exposures or wider apertures to achieve effects such as motion blur or a shallower depth of field. This variable ND filter supports 3–7 stops of light reduction and is designed to preserve image quality while allowing greater creative control over exposure.
Advantages
The filter features double-sided multilayer green coating on both surfaces to reduce reflections from the scene and the filter itself, and double-sided polishing to balance light transmission and maintain high-definition images. Advanced coating technology provides hydrophobic and scratch-resistant properties so water and dirt bead off the surface rather than smearing, and the glass resists abrasion in challenging outdoor conditions. Built with technology to minimize the "X" pattern commonly seen on some variable ND filters when used with wide-angle lenses.
Key specifications
Type: Variable ND filter
Light reduction: 3–7 stops
Coating: Double-sided multilayer green coating
Surface finish: Double-sided polishing
Special properties: Hydrophobic and scratch resistant multilayer nanometer coatings
Image artifact control: Reduced "X" cross on wide-angle lenses
How to use
Attach the filter to the front of the lens using the appropriate thread size. Rotate the adjustable ring to set the desired amount of light reduction between 3 and 7 stops while monitoring exposure or using the camera's histogram. For long exposures or wider apertures, check the image for any residual artifacts at extreme settings and adjust composition or focal length if necessary to avoid vignetting or the rare appearance of cross patterns.
Recommendations
Clean the filter with a soft microfiber cloth and, if needed, a few drops of lens cleaner to maintain the hydrophobic coating. Store the filter in its protective case when not in use. When shooting wide-angle, verify results at different rotations to ensure minimal cross pattern and optimal image quality.
