This Leica Elpro 52mm Close-Up Lens for their M and TL lenses offers the ability to achieve macro-like results with camera lenses that have 52mm, 49mm, or 46mm front filter threads. A close-up filter or 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.
The lens in this Leica Elpro 52 Set is constructed from optical glass, which includes anti-reflection coatings that offer improved clarity as well as more effective prevention of internal ghosting and reflections. Also included is a step-up ring that permits the use of the close-up lens on a camera lens with 49mm front filter threads, a step-up ring that permits the use of the close-up lens on a camera lens with 46mm front filter threads, and a leather pouch to store or transport the entire Elpro 52 Set.
