B+W 37mm Close-Up +2 SC NL 2 Lens

The B+W 37mm Close-Up +2 SC NL 2 Lens offers the ability to achieve macro-like results with camera lenses that have 37mm 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.
