Optical imaging lens assembly

An optical imaging lens assembly, comprising:

• a lens barrel, and a lens group and at least seven spacing elements accommodated in the lens barrel,
• wherein the lens group comprises a first lens having a positive refractive power, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power, a fifth lens having a negative refractive power, a sixth lens having a positive refractive power, a seventh lens having a positive refractive power and an eighth lens having a negative refractive power that are arranged in sequence along an optical axis from an object side to an image side, wherein at least one lens in the first lens to the fourth lens is a meniscus lens;
• and a distance from a center of an effective-diameter portion of an object-side surface of the eighth lens to a rear-end surface of the lens barrel along the optical axis is less than a distance from an edge of the effective-diameter portion of the object-side surface of the eighth lens to the rear-end surface of the lens barrel along the optical axis;
• the at least seven spacing elements comprise a fifth spacing element that is disposed on an image side of the fifth lens and is partially in contact with the fifth lens, and at least one spacing element disposed between the seventh lens and the eighth lens;
• and
• the optical imaging lens assembly satisfies:
• (R9×R10)/(d5s×d5m)>0.5,
• wherein R9 is a radius of curvature of an object-side surface of the fifth lens, R10 is a radius of curvature of an image-side surface of the fifth lens, d5s is an inner diameter of an object-side surface of the fifth spacing element, and d5m is an inner diameter of an image-side surface of the fifth spacing element.
