Claim 13:
14. The image lens assembly of claim 1, wherein a sum of central thicknesses of all lens elements of the image lens assembly is ΣCT, a difference value of an axial distance between the image-side surface of the seventh lens element and the image surface in long shot mode with a maximum field of view to an axial distance between the image-side surface of the seventh lens element and the image surface in long shot mode with a minimum field of view is ΔBL, a difference value of an axial distance between the object-side surface of the first lens element and the image-side surface of the seventh lens element in long shot mode with the maximum field of view to an axial distance between the object-side surface of the first lens element and the image-side surface of the seventh lens element in long shot mode with the minimum field of view is ΔTd, and the following conditions are satisfied:

|ΔBL|/ΣCT<0.01; and

|ΔTP|/ΣCT<0.01.
