Hoya 43mm Close-up Filter Set with +1, +2 & +4 Macro Lenses.
Available in +1, +2, and +4 diopters for close-up photography. Close-up lenses are high-quality optical magnifying lenses which shorten the close-focusing distance of the lens. It allows the lens to go closer to the subject than before and to achieve a larger image scale.
Use lenses individually or in combination for maximum effect
