No “X” cross on images: The filter has a frame self-locking technology. When rotating to the Min end or ND32 stops, the frame is automatically locked, This makes it easier to achieve effects such as a shallower depth of field or blurred motion, Avoiding “X” spot on images.
Nano Coating:Our optical engineers developed new nano coating layer technology, called nanotec, from the ground up to repel dirt, water,oil and other elements by beading rather than absorbing and smearing. Set in our workhorse and built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.
