Abstract
An imaging lens consists of a front group having a positive refractive power, a stop, and a rear group having a positive refractive power. The front group is composed of a front group negative lens group constituted by two or more negative lenses and a front group positive lens group constituted by a plurality of lenses with a positive lens being disposed on the most object side to have a positive refractive power, in order from the object side. The rear group includes at least one negative lens. When the Abbe number of the most object side positive lens in the front group positive lens group with respect to the d-line is taken as νp, the imaging lens satisfies a conditional expression (1): νp<30.
