Optical imaging system including seven lenses of +−+−++− or +−+−−+− refractive powers

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 disposed in order from an object side, wherein TTL/(2*IMG HT)≤0.6 is satisfied, where TTL is a distance on an optical axis from an object-side surface of the fi...

Summary: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 disposed in order from an object side, wherein TTL/(2*IMG HT)≤0.6 is satisfied, where TTL is a distance on an optical axis from an object-side surface of the first lens to an imaging plane of an image sensor, and IMG HT is half a diagonal length of the imaging plane of the image sensor.
