The one difference between newer lenses and the older ones relates to the fact digital sensors are more reflective that film, which can reduce the contrast compared with film. Hence newer lenses tend to do a better job of minimizing reflection issues from the sensor.
Since I came to EOS from Olympus cameras, I only know the newer Canon lenses. The 16-35 is a nice lens. The Lens hood makes the lens appear much larger. In the 24-35mm range, I like it better than the 24-105/4.
