Image taking lens |
| abstract |
An image taking lens LA comprises an aperture S 1 , a first lens L 1 and a second lens L 2 which are arranged in this order from an object side to an image side. The first lens L 1 has a positive power and a meniscus shape with a convex surface facing an object; and the second lens L 2 has a positive power with a convex surface facing an image. The first lens L 1 and the second lens L 2 satisfy the following formulae (1) and (2):n n0.30< R 1/ R 2<0.65 (1)n n0.30< d 3/ F <0.50 (2)n nThis image taking lens formed of the two lenses is small in size and has a high optical performance, in which the entire image taking lens has a short focal length. |
