IMAGING LENS AND IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an imaging lens which can achieve downsizing, wide-angle, low cost, small F-number and better optical performance. SOLUTION: The imaging lens 1 includes a first lens L1 having a negative power and including a concave surface directed to an image side, a second lens L2 having a positive power, a third lens L3 having a positive power, an aperture diaphragm, a fourth lens L4, which is a biconcave lens having a negative power, a fifth lens L5 having a positive power and including a convex surface directed to the image side, and a sixth lens L6 having a positive power and including a convex surface directed an object side, which are arranged in this order from the object side. The Abbe number of a material forming the fourth lens with respect to the d-line is 30 or less. When the focal length of the entire lens system is f and a composite focal length from the fourth lens L4 to the sixth lens L6 is f456, the imaging lens 1 satisfies a conditional expression (1): 1.00
