| titleOfInvention | Image pickup apparatus and optical apparatus using the same |
| abstract | An image pickup apparatus includes an optical system which includes a plurality of lenses, and an image sensor which is disposed at an image position of the optical system, wherein the optical system includes in order from an object side, a first lens having a negative refractive power, an aperture stop, a second lens having a positive refractive power, and a third lens, and an object-side surface of the third lens has a shape which his concave toward the object side, and each of the first lens, the second lens, and the third lens is formed of a material having a refractive index not higher than 1.70, and the following conditional expression (1) is satisfied: n 0.5<Φ L/IH <3.0 (1),n where, IH denotes a maximum image height, and Φ1L denotes an effective aperture at an object-side surface of the first lens. |
