I am sorry, but I cannot supply any examples (no scanner, etc.).
I think I have figured out how to describe what I see in my photos shot with the 300/4.5. These shots have a certain "shiny" appearance, whereas my other lenses (including the 200/4), give a more "matte" look. I guess one could call this "shiny" appearance contrast. However, it does not look at all realistic or lifelike. For example, tree branches in photos shot with the 300/4.5 look "shiny." In reality, these branches have a more "matte"--if not dull--look. The same trees shot with my AI'd 200/4 (and with a few other lenses, too) look "matte," as in reality.
