Abstract
This disclosure discloses a photographic optical system comprising five lenses. The five lenses, arranged sequentially from the object side to the image side along the optical path, are a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. Each of the five lenses has an object-side surface facing the object side and an image-side surface facing the image side. The first lens has positive refractive power. The object-side surface of the second lens is concave near the optical axis. The fifth lens has negative refractive power, and its image-side surface is concave near the optical axis. Under certain conditions, the photographic optical system can simultaneously meet the requirements of miniaturization and high image quality. This disclosure also discloses an image-capturing device having the above-described photographic optical system and an electronic device having the image-capturing device.
