B+W 52mm Close-Up +5 SC NL 5 Lens

The B+W 52mm Close-Up +5 SC NL 5 Lens offers the ability to achieve macro-like results with camera lenses that have 52mm front filter threads. A close-up lens is a magnifier that optically decreases the focal length of a camera lens placed behind it. This effect lessens the minimum focus distance between the camera lens and a subject. Magnification can then be obtained by decreasing the distance between the subject and the combined camera lens and close-up lens.
