Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially disposed on an optical axis from an object side toward an image side. A distance from an object-side surface of the first lens to an imaging plane of an image sensor is TTL, an overall focal length of an optical system including the first to sixth lenses is F, and TTL/F≤0.83. An optical axis distance between the second lens and the third lens is D23, an optical axis distance between the third lens and the fourth lens is D34, and 2.2<D23/D34<5.4.
