Abstract
Provided is a photographing lens optical system. The lens optical system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens sequentially arranged from an object to an image sensor. The first lens may have a negative (−) refractive power and have an exit surface that is concave with respect to the image sensor. The lens optical system may satisfy at least one of a condition 100°<FOV<200° and a condition 1<TTL/ImgH<2. Herein, FOV denotes an angle of view of the lens optical system, TTL denotes a distance from an incidence surface of the first lens to the image sensor, and ImgH denotes a diagonal length of a maximum pixel region of the image sensor.
