Classification: CPC G | IPC G

Claim 0:
1. An optical imaging system comprising:
a first lens group comprising a first lens, the first lens being disposed closest to an object side of the optical imaging system among all lenses of the optical imaging system; and
a second lens group disposed between the first lens group and an imaging plane of the optical imaging system,
wherein the first lens group is configured to be movable to increase and decrease a distance between the first lens group and the second lens group, and
a ratio TLs/TL of a length TLs of the optical imaging system along an optical axis of the optical imaging system from an object-side surface of the first lens to the imaging plane in a state in which the first lens group has been moved to decrease the distance between the first lens group and the second lens group to a length TL of the optical imaging system along the optical axis from the object-side surface of the first lens to the imaging plane in a state in which the first lens group has been moved to increase the distance between the first lens group and the second lens group is greater than 0.70 and less than 0.79.
