Abstract: Disclosed are a high-performance imaging lens which has a comparatively wide angle and in which, in particular, distortion is satisfactory corrected, and an imaging apparatus including the imaging lens. The imaging lens consists of, in order from an object side, a first lens L1 having negative refractive power, a second lens L2 having negative refractive power, a third lens L3 having positive refractive power, a fourth lens L4 having positive refractive power, a fifth lens L5, and a sixth lens L6. One of the fifth lens L5 and the sixth lens L6 has positive refractive power, and the other lens has negative refractive power. The following conditional expressions (1) and (2) are satisfied. −0.37

Abstract: Provided are an imaging lens and an Imaging apparatus which includes this imaging lens. The imaging lens consists of, in order from an object side: a front group GF; a diaphragm St; and a rear group GR. The front group GF consists of, in order from the object side: a first lens L1 that is convex toward the object side and has a negative refractive power; a second lens L2 that has a negative refractive power; and a third lens L3 that has a positive refractive power. The rear group GR consists of, in order from the object side: a fourth lens L4 that has a positive refractive power; a fifth lens L5 that has a positive refractive power; a sixth lens L6 that has a negative refractive power; a seventh lens L7 that has a positive refractive power; and an eighth lens L8 that has a negative refractive power.

Abstract: Provided are an imaging lens that has a small amount of focus shift caused by temperature fluctuation and an imaging apparatus that has this imaging lens. The imaging lens consists of, in order from an object side: a first lens that is convex toward the object side and has a negative refractive power; a second lens that has a negative refractive power; a third lens that has a positive refractive power; a fourth lens that has a positive refractive power; a fifth lens that has a positive refractive power; and a sixth lens that has a negative refractive power. The imaging lens satisfies the following conditional expressions (1) to (4). −0.89
