The Carl Zeiss 58mm ultraviolet filter meets the highest demands on mechanical quality and can be quickly and easily changed. High-quality optical glass is developed to meet the performance needs of Zeiss lenses. The proven T* coating minimizes light reflections on glass-air surfaces and improves transmission. In addition to the filter function, the front lens element is protected against contamination and scratches. With the standard thread diameter of 58mm, the filter also fits the lenses of other manufacturers.
