Abstract:
A compact low-profile low-cost imaging lens with a small F-value which offers a wide field of view and corrects aberrations properly. Its elements are spaced from each other and arranged from an object side to an image side as follows: a first positive lens having a convex object-side surface; a second negative lens; a third positive or negative lens; a fourth positive or negative lens; a fifth positive or negative lens; a sixth positive or negative lens; and a seventh lens as a double-sided aspheric lens having a concave image-side surface. The third to sixth lenses each have at least one aspheric surface. The aspheric image-side surface of the seventh lens has a pole-change point off an optical axis. The imaging lens satisfies a conditional expression −1.0<f1/f2<−0.15, where f1 denotes focal length of the first lens, and f2 denotes focal length of the second lens.

Claim (Index 30):
The imaging lens according to claim  1 , wherein an expression (21) is satisfied:\n f/EPD<2.40, where \u2003\u2003(21) f: an overall focal length of the imaging lens, and EPD: entrance pupil diameter.
