摘要： A photographing lens includes an aperture stop having a predetermined aperture, a first lens having a positive refractive power and a convex surface facing the object side, a second lens having a positive refractive power and aspherical surfaces on both sides, the object-side aspherical surface being concave, and a third lens having a negative refractive power and aspherical surfaces on both sides, the object side surface being convex. The aperture stop and the first, second, and third lenses are arranged in order from the object side toward the image-plane side. With such a three-unit, three element lens configuration, a proper back focus is ensured, aberrations are properly corrected, and the total lens length and thickness of the photographing lens are reduced. The photographing lens can be suitably applied to high-resolution image pickup devices with a million pixels or more.

摘要： A zoom lens includes, in sequence from the object side: a first lens group with an overall negative refractive power; and a second lens group with an overall positive refractive power. A zoom factor changes by moving the second lens group. Focal adjustments are made by moving the first lens group accompanied by the change of the zoom factor made by the movement of the second lens group. The first lens group includes a first lens having a negative refractive power and a second lens having a positive refractive power. The second lens group includes a third lens having a positive refractive power, a fourth lens with a positive refractive power and a fifth lens with a negative refractive power bonded together, and a sixth lens with a positive refractive power. The bonded lenses form a meniscus shape with a convex surface facing the object side. The resulting lens is short in length, compact, thin, and suitable for digital still cameras.
