ND & CPL Filter 2 in 1
There is an ND and CPL filter combine into one filter. When you adjust the nd filter stops well, then rotate the sawtooth frame border, which can achieve the nd filter and cpl filter features as the same time,you need not use cpl ffilter add a nd filter.
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.
