摘要:
The present technology relates to an imaging lens, a camera module, and an imaging apparatus that make it possible to obtain an imaging lens that has a small size and excellent optical performance. Provided is an imaging lens including a front group placed on an object side, a rear group placed on an imaging surface side, and a diaphragm placed between the front group and the rear group. The front group includes at least one lens having negative refractive power and at least one lens having positive refractive power, and the rear group includes at least one lens having negative refractive power. A lens surface closest to an imaging surface has an aspheric shape with an inflection point. Furthermore, a difference between a maximum value of an Abbe number of the lens having negative refractive power of the front group and a minimum value of an Abbe number of the lens having positive refractive power of the front group is larger than 14. Thus, an imaging lens that has a small size and excellent optical performan
