Imaging lens and imaging apparatus

An imaging lens consisting of, in order from an object side to an image side:

• a first lens group;
• a second lens group that has a positive refractive power;
• and
• a third lens group that has a negative refractive power,
• wherein the first lens group includes, successively in order from a position closest to the object side to the image side, two negative lenses and a positive lens,
• the second lens group includes a positive lens and a negative lens,
• during focusing from an object at infinity to a closest object, the first lens group remains stationary with respect to an image plane, and the second lens group moves along an optical axis,
• assuming that a focal length of the first lens group is f1, and
• a focal length of the second lens group is f2,
• Conditional Expression (1) is satisfied:
• −0.5<f2/f1<0.5 (1), and
• assuming that a focal length of the third lens group is f3, Conditional Expression (5) is satisfied:
• −1<f3/f1<0.5 (5).
