Zoom lens and imaging apparatus

A zoom lens consisting of a first lens group having a negative refractive power and a second lens group having a positive refractive power, disposed in order from the object side, wherein:

• zooming is performed by moving the first lens group and the second lens group;
• the first lens group consists of a first lens having a negative refractive power, a second lens, a third lens having a negative refractive power, and a fourth lens having a positive refractive power;
• the second lens group consists of four lenses;
• and
• when the focal length of the second lens from the object side in the first lens group is taken as fG12, the focal length of the entire system at the wide angle end is taken as fw, 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 satisfies conditional expressions given below:
• 0.00<fw/f2<0.50 (1-1);
• and
• −0.09<f1/fG12<0.16 (2-1).
