I've just had an idea. Considering the lens is still in production since 1993 (according to Wikipedia), do you think the newer (like from the past ten years or something) ones could possibly have better image quality due to better manufacturing process or something?

In any manufacturing quality control and consistency tends to increase over time, this tends to mean that later editions are better, they also tend to make minor improvements in quality and cost reductions. On the whole it may be slightly less over engineered, but more consistent.
