Adorama 37mm Close-up Filter Set with +1, +2 & +4 Macro Lenses.

• 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.

Close-up filters are available in three diopters (strengths). Close-up +1 Diopter (101), Close-up +2 Diopter (102), Close-up +4 Diopter (104)
