1. An optical imaging lens group, along an optical axis from an object side to an image side sequentially comprising: an autofocus component, a first lens, a second lens, a third lens, a fourth lens, and at least one subsequent lens, wherein,
a radius of curvature of an image-side surface of the autofocus component is variable; and
there is an interval between each two adjacent lenses among the first lens to the at least one subsequent lens,
wherein a total effective focal length f of the optical imaging lens group and an effective focal length f4 of the fourth lens satisfy: 0<f4/f<0.62,
wherein a spaced interval T12 between the first lens and the second lens on the optical axis and a spaced interval T23 between the second lens and the third lens on the optical axis satisfy: 1.7<T23/T12<2.08.
