Original Abstract Submitted
an optical imaging system includes a first lens group having a first group of lenses. a foremost lens of the first group of lenses is a lens closest to an object side and has a positive refractive power. the optical imaging system also includes a second lens group having a second group of lenses. a rearmost lens of the second group of lenses is a lens closest to an imaging plane and has convex surfaces. the first and second lens groups are sequentially disposed from the object side to an imaging plane. an expression tl/f1<2.0 is satisfied, where tl represents a distance from an object-side surface of the foremost lens to the imaging plane and f1 represents a focal length of the foremost lens.
