Original Abstract Submitted
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially disposed in ascending numerical order along an optical axis of the optical imaging system from an object side of the optical imaging system toward an imaging surface of an image sensor, wherein f/f2+f/f3<−0.4 is satisfied, where f is a focal length of the optical imaging system, f2 is a focal length of the second lens, and f3 is a focal length of the third lens, and TTL/(2*IMG HT)<0.69 is satisfied, where TTL is a distance along the optical axis from an object-side surface of the first lens to the imaging surface of the image sensor, and IMG HT is one half of a diagonal length of the imaging surface of the image sensor.
