1. An optical imaging lens assembly, comprising, sequentially along an optical axis from an object side to an image side:
a first lens, having a positive refractive power;
a second lens, having a negative refractive power; and
a third lens, having a positive refractive power,
wherein, the optical imaging lens assembly satisfies:
0.5<M<1.5,
where, M is a magnification of the optical imaging lens assembly, and
wherein an axial distance SAG12 measured along the optical axis, from an intersection point of an image-side surface of the first lens and the optical axis to a vertex of an effective radius of the image-side surface of the first lens, an axial distance SAG32 measured along the optical axis, from an intersection point of an image-side surface of the third lens and the optical axis to a vertex of an effective radius of the image-side surface of the third lens, an axial distance SAG31 measured along the optical axis, from an intersection point of an object-side surface of the third lens and the optical axis to a vertex of an effective radius of the object-side surface of the third lens satisfy:
|(SAG12+SAG32)/SAG31|<1.5.
