摘要： 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 along an optical axis from an object side toward an image side. The fifth lens has a positive refractive power, a focal length of the fifth lens is smaller than an overall focal length of the optical imaging system, and −0.38≤R10/f≤−0.32, where R10 is a radius of curvature of an image-side surface of the fifth lens and f is the overall focal length of the optical imaging system.
