Abstract
A narrow-profile lens group for long-distance image capture includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, from object side to imaging side. Each lens has two surfaces, the group meeting formula 0.85<D/TTL<1.05, 0.37<(D*0.5)/F<0.45, where D is the maximum imaging circle diameter on the imaging surface; TTL is the distance from the center point of a surface of the first lens adjacent to the object side to the imaging surface, and F is the focal length of the telephoto lens.
