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, sequentially arranged from an object side, wherein TTL/(2*Img HT)<0.7, where a distance on an optical axis from an object-side surface of the first lens to...

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, sequentially arranged from an object side, wherein TTL/(2*Img HT)<0.7, where a distance on an optical axis from an object-side surface of the first lens to an imaging plane of an image sensor is TTL, and half of a diagonal length of the imaging plane of the image sensor is Img HT, and Fno<1.9, where an F-number of the optical imaging system is Fno.
