Abstract
An imaging lens system includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially disposed from an object side. The fourth lens has negative refractive power and the fifth lens has negative refractive power, and a ratio (TTL/2ImgHT) between a distance (TTL) from an object-side surface of the first lens to an imaging plane and a diagonal length (2ImgHT) of the imaging plane is 0.6 or less.
