Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 17:
18. An optical imaging system comprising:
a first lens group;
a second lens group;
a reflecting member disposed on an image side of the second lens group and configured to direct light that has passed through the second lens group to an image sensor,
wherein one or both of the first lens group and the second lens group are configured to be moved along an optical axis such that an interval between the first lens group and the second lens group along the optical axis is variable between a maximum interval and a minimum interval, and
the reflecting member is configured to be moved such that a distance that the light that has passed through the second lens group travels between the second lens group and the reflecting member is variable,
wherein fl/fh<0.7, where fl is an overall focal length of the optical imaging system when the first lens group and the second lens group are spaced by the maximum interval, and fh is an overall focal length of the optical imaging system when the first lens group and the second lens group are spaced by the minimum interval.
