1. A zoom lens comprising, in order from an object along an optical axis:
a first lens group having a negative refractive power;
a second lens group having a positive refractive power;
a third lens group having a negative refractive power; and
a fourth lens group, wherein
when the zoom lens performs zooming, the first lens group, the second lens group, the third lens group, and the fourth lens group move along the optical axis, a distance between the first and second lens groups changes, a distance between the second and third lens groups changes, and a distance between the third and fourth lens groups changes,
the first lens group comprises, in order from the object along the optical axis, a negative lens, a negative lens, a negative lens, and a positive lens,
the third lens group consists of one lens component having negative refractive power, and
the following conditional expression is satisfied:
1.500<(−f3)/fw<7.000
where
f3: a focal length of the third lens group,
fw: a focal length of the zoom lens in a wide-angle end state.
