The 39mm 3Peak UV Filter from Gobe is a general-use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter.
This filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity and features 16 layers of anti-reflection coatings on each side. These coatings also offer scratch protection to the filter substrate 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 Schott B270 glass is set within a magnalium-alloy filter ring.
