<p>[Problem] To configure an image capturing lens so that the image capturing lens has a wide image angle, is compact, and has high optical performance. [Solution] An image capturing lens comprises, in order from the object side, a first lens group (G1) which has negative refractive power and a second lens group (G2) which has positive refractive power. The first lens group (G1) comprises a first-group first lens (L11) which is a single lens having negative refractive power. The second lens group (G2) comprises, in order from the object side, a second-group first lens (L21) which has positive refractive power, a second-group second lens (L22) which has positive refractive power, and a second-group third lens (L23) which has negative refractive power. If f1 is the focal length of the first-group first lens (L11), f2 is the focal length of the second-group first lens (L21), and f is the focal length of the entire lens system, the conditional expression (1) 0 < f2/f < 1.5 and the conditional expression (2) 0 < |f1/f2| < 0.9 are satisfied at the same time.</p> |
