Its obvious that the focal lenghth of the thin lens will be high then the thick lens. As in your eye  when you see the object at very far distance the focal length of the eye lens become maximum and lens become thin. 
 
The aperature is the diameter of the curve part of the lenst.it may effect .But one should focus on the radius of the curvature of the two lens surfaces R1 and R2.
