This 4-stop FotodioX WonderPana 145 Core Unit Tamron 15-30mm Lens Filtersfeatures a filter ring with 145mm front filter threads. With a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, this filter includes multiple layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. This filter is constructed from optical glass for clarity as well as color fidelity and features an aluminum-alloy filter ring for durability while remaining lightweight.
