An optical imaging lens assembly is provided. The optical imaging lens includes 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) which are provided in sequence from an object side to an image side along an optical axis and have refractive powers. The first lens has a positive refractive power. The fourth lens has a positive refractive power. The sixth lens has a negative refractive power. The seventh lens has a negative refractive power. An object-side surface (S7) of the fourth lens is a concave surface, and an image-side surface (S8) is a convex surface. An object-side surface (S9) of the fifth lens is a convex surface.
An optical imaging lens assembly, comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens which are provided in sequence from an object side to an image side along an optical axis and have refractive powers, wherein
The optical imaging lens assembly as claimed in 1, wherein an effective focal length f of the optical imaging lens assembly and an Entrance Pupil Diameter (EPD) of the optical imaging lens assembly satisfy the following relationship:
The optical imaging lens assembly as claimed in 1, wherein a radius of curvature R3 of an object-side surface of the second lens and a radius of curvature R4 of an image-side surface of the second lens satisfy the following relationship:
The optical imaging lens assembly as claimed in 1, wherein an effective focal length f1 of the first lens and an effective focal length f7 of the seventh lens satisfy the following relationship:
An optical imaging lens assembly, comprising, sequentially a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens which are provided in sequence from an object side to an image side along an optical axis and have refractive powers, wherein
