These filters won't go anywhere until you take them off your lens. With available brass threaded bases of 67mm, 72mm, 77mm, and 82mm, Helix easily covers your entire lens arsenal. 1x ND8 filter, 1x front, 1x rear defender. ND filters extend your exposure time. A neutral density filter (ND filter) or gray filter blocks a portion of the incoming light. With a gray filter, you significantly extend the exposure time, achieving effects like blurred water or preventing overexposure in bright sunlight with an open aperture.
