Abstract
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 and an eighth lens disposed sequentially from an object side The first lens and the second lens each have a positive refractive power, and the third lens has a negative refractive power, and D12/D_MAX<0.15 is satisfied, where D12 is a distance on an optical axis between an image-side surface of the first lens and an object-side surface of the second lens, and D_MAX is a greatest distance among distances between neighboring lenses.
