Abstract
An optical imaging system is provided. The 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 disposed in order from an object side to an imaging side. The first lens has positive refractive power, and the second lens has negative refractive power, and TTL/(2×IMG HT)<0.6 and −0.1<SAG42/TTL<0 are satisfied, where TTL is a distance from an object-side surface of the first lens to an imaging plane on an optical axis, IMG HT is equal to half a diagonal length of the imaging plane, and SAG42 is a SAG value at an end of an effective aperture of an image-side surface of the fourth lens.
