Provided is a zoom imaging device comprising a mount section 21, a zoom lens 22 for forming an image of light that enters from the mount section 21, and an imaging element 23 arranged in an image formation position. The zoom lens 22 comprises, in order from the image 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 lens group having a negative refractive power. The second lens group G2 is a focus lens group. The zoom imaging device is characterized in that when magnification is varied from the wide-angle end to the telephoto end, the third lens group G3 and the lens group that has a negative refractive power and that is positioned further to the object side than the third lens group move and satisfy the following conditional expression (1): φL1 < φ3GL1. |
