Abstract:
A macro lens includes an object-side lens unit having a positive refractive power, a first focusing lens unit having a negative refractive power, a second focusing lens unit having a positive refractive power, an aperture stop, an intermediate lens unit which includes a lens component having a positive refractive power, and a wobbling lens unit. The aperture stop and the intermediate lens unit are disposed between the first focusing lens unit and the second focusing lens unit, the aperture stop is adjacent to the lens component having a positive refractive power, and the following conditional expressions (1), (2), and (3) are satisfied: 2
