Claim 8:
9. An optical imaging system comprising:
a first lens group disposed on an optical axis of the optical imaging system at an object side of the optical imaging system; and
a second lens group disposed on the optical axis between the first lens group and an imaging plane of the optical imaging system,
wherein the first lens group is configured to be movable between a first position at which a first length of the optical imaging system along the optical axis from an object-side surface of the first lens group to the imaging plane is TL, and a second position at which a second length of the optical imaging system along the optical axis from the object-side surface of the first lens group to the imaging plane is TLs, and
TL and TLs satisfy the following conditional expression:

0.70<TLs/TL<0.79.
