Inventor includes Peng, Haichao.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: Disclosed in the present invention is a photographic optical lens. The photographic optical lens consists of a first prism having a positive refractive power, a first lens having a negative refractive power, a second lens having a positive refractive power, a third lens, a fourth lens and a fifth lens, which are successively arranged from an object side to an image side; a reflective surface is provided between an object-side surface and an image-side surface of the first prism; the first lens, the second lens and the third lens form a first lens group, the fourth lens and the fifth lens form a second lens group, and the first lens group is arranged to be movable and adjustable along the optical axis of the photographic optical lens, such that the photographic optical lens is switched between a first state and a second state, wherein the focal length of the photographic optical lens in the first state is fA, the image height of the photographic optical lens is IH, and the following relational expression is satisfied: 4.00=fA/IH=5.50. The photographic optical lens of the present invention can achieve a large-aperture periscopic design, and has good optical performance.
