摘要： An optical imaging lens includes a first lens to a sixth lens and correspondingly forms a first focusing state and a second focusing state. The first lens element has positive refracting power, a periphery region of the image-side surface of a fifth lens element is concave, an optical axis region of the image-side surface of the sixth lens element is concave, a periphery region of the image-side surface of the sixth lens element is convex. Lens elements included by the optical imaging lens are only six lens elements. The rear lens group enables the optical imaging lens to form a first focusing state and a second focusing state to satisfy TTL*ΔHFOV/ΔG≤19.500 degrees.

摘要： A lens barrel includes a lens barrel surrounding wall and a cover member. The lens barrel surrounding wall surrounds an optical axis. The lens barrel surrounding wall includes a lens element accommodating portion abutted against lens elements. The lens barrel surrounding wall has an object side connecting surface closest to an object side and facing the object side. An inner diameter of the lens element accommodating portion closest to the object side is greater than an inner diameter of the lens element accommodating portion closest to an image side. The cover member has an image side connecting surface facing the image side. The image side connecting surface of the cover member is fixed on the object side connecting surface of the lens barrel surrounding wall, wherein a maximum outer diameter of the cover member is less than or equal to a maximum outer diameter of the lens barrel surrounding wall.
