K&F Concept Nano-Xcel Series ND Filter

The filter uses a magnetic ring that screws onto your lens, allowing the ND filter to snap into place instantly. This eliminates the need to screw and unscrew the filter, making it much faster to swap or remove when lighting conditions change.

No, the frame is specifically designed to be ultra-slim at 5.3mm. This low profile prevents the edges of the filter from appearing in your frame, even when shooting at wider focal lengths.

The filter uses high-quality Japanese AGC optical glass with 28 multi-layer coatings, which are designed to maintain color neutrality. While some extreme ND filters can introduce a slight color cast, this model is engineered to keep your colors accurate and consistent.

Yes, it is built for field use. The aluminum-magnesium alloy frame is durable, and the glass features multi-layer coatings that provide water and scratch resistance, making it easier to clean and protect against the elements.

The magnetic system is designed for quick changes, but it is not intended for stacking multiple filters on top of the magnetic mount. If you need to use a circular polarizer or another filter, you would typically need to swap the ND filter out for the other.
