Optical imaging lens assembly, image capturing apparatus and electronic device

An optical imaging lens assembly, comprising, in order from an object side to an image side:

• a first lens element having negative refractive power;
• a second lens element with negative refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof;
• a third lens element having positive refractive power;
• a fourth lens element having positive refractive power;
• a fifth lens element having positive refractive power;
• and
• a sixth lens element having negative refractive power;
• wherein the optical imaging lens assembly has a total of six lens elements;
• and wherein a central thickness of the second lens element is CT2, a central thickness of the third lens element is CT3, a focal length of the optical imaging lens assembly is f, an axial distance between the first lens element and the second lens element is T12, an axial distance between the image-side surface of the sixth lens element and an image surface is BL, a sum of axial distances between respective two adjacent lens elements of the optical imaging lens assembly is ΣAT, an entrance pupil diameter of the optical imaging lens assembly is EPD, and the following conditions are satisfied:
• 0<CT3/CT2<1.0;
• 0<f/T12<5.50;
• 0.15<BL/ΣAT<1.70;
