Imaging lens and imaging apparatus equipped with the imaging lens

An imaging lens consisting of seven lenses, composed of, in order from the object side, a first lens having a negative refractive power with the object side surface having a concave shape, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens having a negative refractive power with the image side surface having a concave shape with at least one inflection point located radially inward of the intersection between the image side surface and the principal ray of the maximum angle of view, wherein:

• an aperture stop is provided between the first lens and the fifth lens;
• one of the second lens and the third lens has a positive refractive power and the other of the second lens and the third lens has a negative refractive power;
• one of the fifth lens and the sixth lens has a positive refractive power and the other of the fifth lens and the sixth lens has a negative refractive power;
• and the following conditional expressions are satisfied:
• 30<νP1−νN1<50 (1)
• 30<νP2−νN2<50 (2)
• where
• νP1 is the Abbe number of either one of the second lens and the third lens having a positive refractive power with respect to the d-line;
• νN1 is the Abbe number of either one of the second lens and the third lens having a negative refractive power with respect to the d-line;
• νP2 is the Abbe number of either one of the fifth lens and the sixth lens having a positive refractive power with respect to the d-line;
• and
• νN2 is the Abbe number of either one of the fifth lens and the sixth lens having a negative refractive power with respect to the d-line.
