摘要： An optical imaging lens includes an aperture, a front lens group and a rear lens group along an optical axis from an object side to an image side. A first lens element of the front lens group is a lens element in a first order from the object side, and a second lens element is in a second order. The first lens element has positive refracting power, and an optical axis region of the object-side surface of the second lens element is convex, or its periphery region is convex. Lens elements included by the optical imaging lens are only five lens elements. The rear lens group enables the optical imaging lens to form a first focusing state and a second focusing state. EFL is an effective focal length of the first focusing state, and EFLA is an effective focal length of the second focusing state to satisfy EFL/EFLA≥1.200.

摘要： An optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element in sequence along an optical axis from an object side to an image side. When the object moves from infinity to macro, the optical imaging lens correspondingly forms a first focusing state and a second focusing state to achieve the focusing purpose. The fifth lens element has negative refracting power, an optical axis region of the object-side surface of the fifth lens element is concave, and an optical axis region of the image-side surface of the fifth lens element is concave. Lens elements included by the optical imaging lens are only five lens elements, and (TTL*ΔHFOV)/ΔG≤19.000 degrees is satisfied.
