The 72mm ND4 2Peak ND 0.6 Filter from Gobe is an ND filter with a 4x filter factor that provides a 2-stop exposure reduction. Its 0.6 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 can 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.
This filter is constructed from optical glass that features 16 layers of anti-reflection coatings on each side. These coatings also offer scratch protection to the filter substrate while promoting clarity as well as color fidelity, and result in an improved beading effect when in contact with water or oil for more efficient cleaning.
For enhanced durability while remaining lightweight, the optical glass is set within a magnalium-alloy filter ring.
