Zoom lens and imaging apparatus

Abstract

In a zoom lens in which a first lens group having a negative refractive power and a second lens group having a positive refractive power are disposed in order from the object side and zooming is performed by moving the first lens group and the second lens group, the first lens group is formed of a first lens having a negative refractive power, a second lens having a positive refractive power, a third lens having a negative refractive power, and a fourth lens having a positive refractive power, disposed in order from the object side. Then, when the focal length of the first lens group is taken as f1 and the focal length of the second lens group is taken as f2, the zoom lens is configured to satisfy a conditional expression give below: 0.00<|f1/f2|<1.04   (1-4).
