These are Fire Crest, they are no longer made in this size, and don’t have the advanced coatings as the firecrest Ultra. However, they don’t need advanced coatings because these go behind the lens, and are not subject to astray light rays. These add no weight on front of the lens, and can be swapped fro different strengths very easily.
