By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. | Material：This ND filter is constructed from optical glass for clarity as well as color fidelity. A thin, aluminum-alloy filter ring minimizes the potential for vignetting, while remaining durable and lightweight. | Coating：To prevent internal ghosting and reflections, the glass features eight layers of multi-coating. These coatings also offer greater protection to a filter substrate waterproof scratch resistant and help it to stay clean for longer than with uncoated filters. | Other：Please verify your camera's lens thread size before ordering.
