A macro lens, an optical device, and a method for manufacturing the macro lens are provided, which obtain the vibration reduction function having the optical performance. A macro lens comprises the first lens group(G1), the second lens group(G2), and the third lens group(G3). The combined refractive power of the second lens group and the first lens group is the positive. The first lens group and the second lens group are mobile in order to change focusing from the infinite distance to the near distance. Each lens group comprises one or more positive lens and one or more negative lens group.
