It's a pity those manual focus FD lenses are no longer compatible with current Canon bodies as this page

really shows how the FD lenses were constructed with really good quality compared with the plastic canon EF lenses of today.
For example look at the quality of the focus ring, and the nice clear markings for distance, dof and aperture and compare that with the "dumbed down" markings that you find on most modern lenses.
