The close-up converter Leica Elpro-S 180 mm is designed exclusively for use with the Leica APO-Elmar-S 180 mm f3.5 (CS) and is screwed into the filter thread of the lens. Exposure settings are identical for the lens without the converter. With the Leica Elpro-S 180 mm fitted, you can focus in the range of 1.1 to 2.7 m (3.6 - 8.8') and achieve a maximum magnification of 1:4.5 at the minimum focusing distance. The imaging quality of the Leica Apo-Elmar-S 180 mm f3.5 is maintained at all aperture and focus settings. The combination of the Leica Apo-Elmar-S 180 mm f3.5 and Leica Elpro-S 180 mm is ideal for beauty and close-up shots with an elaborate lighting setup.
