1. An optical imaging lens assembly, sequentially from an object side to an image side along an optical axis, comprising: a first lens and at least one subsequent lens having refractive power, wherein,
0.6<(TTL/P)*10<1.51,
where TTL is a distance along the optical axis from an object-side surface of the first lens to an image plane of the optical imaging lens assembly, and P is a distance along the optical axis from a to-be-captured object to the object-side surface of the first lens;
0.55<|f/R1|<2.6,
where f is a total effective focal length of the optical imaging lens assembly, and R1 is a radius of curvature of the object-side surface of the first lens; and
0.3<DT12/DT11<1.6,
where DT12 is an effective aperture radius of an image-side surface of the first lens, and DT11 is an effective aperture radius of the object-side surface of the first lens.
