| titleOfInvention | Image-capturing lens, image-capturing device, and portable terminal |
| abstract | Provided is an image-capturing lens composed of five lenses, the image-capturing lens having a smaller size than image-capturing lenses of conventional types and having satisfactorily corrected aberrations. Also provided are an image-capturing device and a portable terminal which are provided with the image-capturing lens. The image capturing lens comprises, in sequence from the object side: a first lens having positive refractive power and having a convex surface facing the object side; a second lens having negative refractive power and having a concave surface facing the image side; a meniscus-shaped third lens having negative refractive power and having a convex surface facing the object side; a fourth lens having positive refractive power and having a convex surface facing the image side; and a fifth lens having negative refractive power and having a concave surface facing the image side. The image-side surface of the fifth lens has a non-spherical shape and has an inflection point at a position other than the intersection point between the optical axis and the image-side surface. The focusing of the image-capturing lens is performed by moving the third lens and the fourth lens together in the optical axis direction, and the image-capturing lens satisfies the following conditional formula (1): 0.75 < f34/f < 1.30, ...(1) where f34 is the composite focal length of the third lens and the fourth lens, and f is the focal length of the entire system of the image-capturing lens. |
