A zoom lens system (10) includes: a primary image forming lens group (11) that forms light from an object side (10a) into an intermediate image (51) and a relay lens group (12) that forms light from the intermediate image (51) into a final image (52), wherein the primary image forming lens group (11) includes, in order from the object side (10a), a first fixed lens group (G1) with negative refractive power, a stop (St), and a second fixed lens group (G2) with positive refractive power, and the relay lens group (12) includes, in order from the object side (10a), a third fixed lens group (G3) with negative refractive power, a first moving lens group (G4) with positive refractive power, and a second moving lens group (G5) with positive refractive power. |
