I am curious to know what is the difference between an AF-S and AF lens. What makes AF-S more costly than AF? Is there any difference in image quality ?

AF-S allows instant manual-focus override simply by grabbing the focus ring at any time.
G means it has no manual aperture control
You will not be able to autofocus AF 50mm 1.8D on cheaper DSLRs
Quality is nearly the same
