Abstract

The present disclosure provides an optical imaging lens assembly and an electronic device. The optical imaging lens assembly includes, sequentially from an object side to an image side along an optical axis, a first lens having a positive refractive power, and an object-side surface of the first lens being a convex surface; a second lens having a negative refractive power; a third lens having a refractive power; a fourth lens having a refractive power; and a fifth lens having a positive refractive power, and an image-side surface of the fifth lens being a concave surface. Here, half of a maximal field-of-view Semi-FOV of the optical imaging lens assembly satisfies Semi-FOV<15°.
