Optical imaging lens assembly

An optical imaging lens assembly, sequentially comprising, from an object side to an image side along an optical axis:

• a first lens with a negative refractive power, an object-side surface thereof is a concave surface, an image-side surface thereof is a convex surface;
• a second lens with a refractive power;
• a diaphragm;
• a third lens with a refractive power, an object-side surface thereof is a convex surface, an image-side surface thereof is a convex surface;
• a fourth lens with a refractive power;
• and
• a fifth lens with a refractive power,
• wherein Semi-FOV is a half of a maximum field of view of the optical imaging lens assembly, and Semi-FOV meets Semi-FOV≥55°;
• and
• SAG11 is a distance from an intersection point of the object-side surface of the first lens and the optical axis to an effective radius vertex of the object-side surface of the first lens on the optical axis, SAG42 is a distance from an intersection point of an image-side surface of the fourth lens and the optical axis to an effective radius vertex of the image-side surface of the fourth lens on the optical axis, and SAG11 and SAG42 meet −2.5<SAG42/SAG11<−1.0.
