Imaging lens and imaging apparatus
An imaging lens consists of, in order from the object side, a negative first lens, a positive second lens, a positive third lens, a negative fourth lens, a positive fifth lens, and a positive sixth lens. The imaging lens satisfies the condition expressions below:f1/f<−1.68  (1-2),−0.7<f4/f  (2),−0.6<(R3+R4)/(R3−R4)<2.2  (11-2), and0.5<f2/f3<4.0  (12),where f1 to f4 are focal lengths of the first to the fourth lenses, f is a focal length of the entire system, R3 is a radius of curvature of the object-side surface of the second lens, and R4 is a radius of curvature of the image-side surface of the second lens.
