how many $$$ have legacy lenses saved for you? and aren't they fun?

Because of the 2X focal length modifier, legacy lenses are all telephoto lenses, so the only use for them that makes any sense is cheap portrait lenses.

Now, if you already own the M.Zuiko 45mm f/1.8, what benefit is there to using a legacy lens? Does anyone have an example of a portrait that was taken with the m.zuiko 45mm, and then taken with a legacy lens, showing that the portrait with the legacy lens is better?
