Patent ID: 11402611

Abstract:
The present disclosure provides an optical imaging system and a camera device equipped with the same. The optical imaging system includes sequentially, from an object side to an image side along an optical axis, a first lens having a positive refractive power, wherein an image-side surface of the first lens gradually changes from a paraxial concave surface to an edge convex surface as the image-side surface moves away from the optical axis; a second lens having a positive refractive power, a convex object-side surface, and a convex image-side surface; a third lens having a negative refractive power; a fourth lens and a fifth lens having a positive refractive power or a negative refractive power, wherein the fifth lens has a convex object-side surface and a concave image-side surface at a paraxial position. A combined refractive power of the fourth lens and the fifth lens is a negative refractive power.
