CAMERA LENS

WIPO Patent Application WO/2020/007080

A1

Provided is a camera lens. The camera lens comprises, sequentially from an object side to an image side along an optical axis, a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4), a fifth lens (E5), a sixth lens (E6) and a seventh lens (E7). The first lens (E1) has a negative focal power; the second lens (E2) has a positive focal power, and the image side surface (S4) thereof is a concave surface; the third lens (E3) has a positive focal power, and the image side surface (S6) thereof is a convex surface; the fourth lens (E4) has a focal power; the fifth lens (E5) has a focal power; the sixth lens (E6) has a positive focal power; the seventh lens (E7) has a negative focal power; and an effective focal distance f2 of the second lens (E2) and a total effective focal distance f of the camera lens meet 2 < f2/f < 4.5. With a rational assignment of the focal power, the surface form and the thickness of the center of the lenses and the axial distances between the lenses, etc., the camera lens can have at least one of the beneficial effects of being ultra-thin, having a large field of view, being excellent in imaging quality, being low in sensitivity, etc.
