K&F Concept Nano-X

ND-------Extend exposure time. Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.

Double-Sided Multilayer Green Coating
Both sides of the filter with enhanced coating, effectively reducing the reflection that came from both the ground and filter itself, double-sided polishing technology balances the light well, ensuring image HD quality.

No "X" Cross on Images
Support 3-7 stops adjustable, K&F Concept utilizes cutting-edge technology you're going to say goodbye to variable ND filters common " X" cross-issue with wide-angle lenses.

Hydrophobic& Scratch Resistant
K&F Concept optical engineers developed multi-layer nanometer coatings technology, from the ground up to repel dirt, water, and other elements by beading rather than absorbing and smearing. To withstand extreme wind, dust, and other abrasive conditions and elements.
