| Zusammenfassung: | An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, and an eleventh lens sequentially arranged in order along an optical axis from an object side of the optical imaging system toward an imaging surface of the optical imaging system, wherein the first lens has a positive refractive power, the second lens has a negative refractive power, at least two lenses sequentially arranged along the optical axis among the first lens to the fourth lens have an Abbe number of less than 38, and TTL/(2×IMG HT) |
