Claim 0:
1. An optical 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 arranged sequentially from an object side to an image side of the optical lens assembly along an optical axis,, wherein,
the first lens has negative refractive power, and an object-side surface of the first lens is convex and an image-side surface of the first lens is concave;
the fourth lens has positive refractive power, and each of an object-side surface and an image-side surface of the fourth lens is convex;
the fifth lens has positive refractive power, and each of an object-side surface and an image-side surface of the fifth lens is convex;
the sixth lens has negative refractive power, and each of an object-side surface and an image-side surface of the sixth lens is concave; and
the seventh lens has positive refractive power, and an object-side surface of the seventh lens is convex, and
wherein a maximum field-of-view FOV of the optical lens assembly, a maximum effective aperture diameter D of the object-side surface of the first lens corresponding to the maximum field-of-view of the optical lens assembly, and an image height h corresponding to the maximum field-of-view of the optical lens assembly satisfy D/h/FOV≤0.035.
