摘要:
The present disclosure discloses an imaging lens assembly, the imaging lens assembly having a total effective focal length f and comprising sequentially, along an optical axis from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. Each of the first lens and the fifth lens has a negative focal power; each of the second lens, the fourth lens, the sixth lens and the seventh lens has a positive focal power or a negative focal power; and the third lens has a positive focal power, and an effective focal length f3 of the third lens and the total effective focal length f satisfy: 1
