Camera lens filter K&F Concept Filter Nano-X 43 mm KF01.1164V1 UV protection

K&F Concept Nano-X 43mm ND2-ND32 XV38 filter is an adjustable neutral density filter designed for 43 mm lenses. It provides variable light reduction from ND2 to ND32, enabling longer exposures and motion blur effects when photographing flowing water, waterfalls or other moving subjects. The filter uses multi-coated AGC glass and a sturdy construction that improves durability and reduces flare. For this filter the compatible lens hood size is 40.5 mm.

Advantages

The variable ND range (ND2–ND32) lets you control exposure without changing filters, making it suitable for landscape and long-exposure photography. High-transmission AGC glass combined with 28 nano-coatings protects against water, scratches and unwanted reflections. The non-slip ring simplifies mounting and removal, while the optical design prevents the cross-stage X-effect that can occur with some variable ND filters.

Key specifications

How to use

Attach the filter to a 43 mm lens by screwing it into the front filter thread, then rotate the adjustable ring to set the desired ND value between ND2 and ND32. Use smaller ND values for slight light reduction and larger values for longer exposures and stronger motion blur. Check composition and exposure on the camera, and if needed use a tripod for stable long exposures. When not in use, store the filter in a protective case to avoid scratches.

Recommendations

Use a 40.5 mm lens hood if required, and avoid stacking multiple variable ND filters to reduce the risk of vignetting and X-effect on wide-angle lenses.
