Abstract
An optical imaging lens assembly sequentially includes, from an object side to an image side along an optical axis, a first lens (E1), second lens (E2), third lens (E3), fourth lens (E4), fifth lens (E5) and sixth lens (E6) with refractive power. The first lens (E1) has a positive refractive power, and an image-side surface (S2) of the first lens is a concave surface. The second lens (E2) has a negative refractive power. The fifth lens (E5) has a negative refractive power, and an object-side surface (S9) of the fifth lens is a concave surface. A distance TTL from an object-side surface (S1) of the first lens (E1) to an imaging surface (S15) of the optical imaging lens assembly and a total effective focal length f of the optical imaging lens assembly satisfy TTL/f≤0.85.
