Patent ID: 8369029

Claim:
An image capturing lens assembly comprising, in order from an object side to an image side: a first lens group comprising only a first lens element with a positive refractive power; and a second lens group comprising, in order from an object side to an image side: a second lens element with a negative refractive power; a third lens element; a fourth lens element; and a fifth lens element; wherein while a distance between an imaged object and the image capturing lens assembly changes from far to near, focusing is performed by moving the first lens group along the optical axis and a distance between the first lens group and an image plane changes from near to far; wherein a focal length of the image capturing lens assembly is f, a focal length of the third lens element is f 3 , a number of lens elements with refractive powers in the image capturing lens assembly is N, and they satisfy the following relations: | f/f 3|<0.7; and 5 ≦N≦ 7.
