1. An optical imaging lens set, from an object side toward an image side in order along an optical axis comprising: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element, the first lens element to the seventh lens element each having an object-side surface facing toward the object side to allow imaging rays to pass through as well as an image-side surface facing toward the image side to allow the imaging rays to pass through, wherein:
the second lens element has an object-side surface with a convex portion in a vicinity of the optical-axis, an object-side surface with a convex portion in a vicinity of its circular periphery and an image-side surface with a concave portion in a vicinity of its circular periphery;
the third lens element has an object-side surface with a convex portion in a vicinity of the optical-axis;
the fourth lens element has an object-side surface with a convex portion in a vicinity of the optical-axis; and
the seventh lens element has an image-side surface with a concave portion in a vicinity of the optical-axis;
wherein lens elements included by the optical imaging lens set are only the seven lens elements described above, ALT is a total thicknesses of all seven lens elements along the optical axis, TL is a distance between the object-side surface of the first lens element and the image-side surface of the seventh lens element along the optical axis, BFL is a distance between the image-side surface of the seventh lens element and an image plane along the optical axis, Tmax is a maximal lens element thickness among the first lens element and the seventh lens element along the optical axis, Tmin is a minimal lens element thickness among the first lens element and the seventh lens element along the optical axis and Gmax is a maximal air gap among the first lens element and the seventh lens element along the optical axis to satisfy ALT/Gmax≤7, TL/BFL≤5.1, and 1.335≤(Tmax+Tmin)/Gmax≤2.776.
