Summary: | An optical imaging system includes a first lens group including at least one lens; a second lens group including at least one lens; and a third lens group including at least one lens, wherein the first lens group, the second lens group, and the third lens group are sequentially disposed in ascending numerical order along an optical axis from an object side toward an image side, each of the second lens group and the third lens group is configured to move along the optical axis relative to the first lens group, the at least one lens of the second lens group includes at least one glass lens and at least one plastic lens, an Abbe number of a glass lens of the second lens group is vg2_g, an Abbe number of a plastic lens of the second lens group is vg2_p, and |vg2_g−vg2_p| is greater than 25. |
