B&W close-up lenses are high-quality optical magnifying lenses which shorten the close-focusing capability of your lens. They are available in different "powers" (diopters).

A +4 lens will allow you to focus even closer than a +2, and so on. These lenses can be used individually or in any combination to achieve ultra-close focus.
