The magnetic Graduated ND filter is clear in the bottom portion of the filter before transitioning to a full 3-stop reduction of light, and can be rotated to allow you to precisely line up the graduation in your image.
Once the magnetic series adapter ring (sold separately) is attached to your lens the filter simply connects safely and securely to the ring and can be installed or removed quickly and easily thanks to the magnetic system.
Please note: This filter does not included an adapter ring, which is sold separately.
