Abstract
The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. Each of the first to the sixth lenses has reactive power. The second lens has positive refractive power. An image-side surface of the fourth lens is concave. A radius of curvature R2 of an image-side surface of the first lens, a radius of curvature R5 of an object-side surface of the third lens and an effective focal length f3 of the third lens satisfy: 2.5<(R2+R5)/f3<11.0.
