Setup, Compatibility & Care
To install, gently screw the 39mm filter threads onto the front of your compatible lens. Ensure the filter is seated properly to avoid cross-threading. When adjusting density, use the square-edge grip to rotate the front element; the hard stops will notify you when you have reached the limit of the ND range. For care, always store the filter in its protective case when not in use. Use a dedicated lens cleaning cloth or a blower to remove dust. If the glass becomes smudged, apply a small amount of lens cleaning solution to a microfiber cloth—never directly to the glass—and wipe in a circular motion.
