    Abstract: The present disclosure discloses an optical imaging lens assembly including a lens barrel, and a lens group and at least seven spacing elements accommodated in the lens barrel. The lens group comprises first to eighth lenses arranged in sequence along an optical axis from an object side to an image side. Here, at least one lens in the first lens to the fourth lens is a meniscus lens, and a refractive power of the seventh lens and a refractive power of the eighth lens are positive-negative opposite. 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.
