Abstract: An optical system (OL) comprising, sequentially along an optical axis from the objective side, a first lens group (G1) having a positive refractive power, a second lens group (G2) having a negative refractive power, a third lens group (G3) having a positive refractive power, and a fourth lens group (G4) having a negative refractive power, wherein, when focusing the optical system, the following conditional expression is satisfied as a result of moving the second lens group (G2) and the third lens group (G3) along the optical axis and changing the interval between adjacent lens groups. 0.20
