On article Did Sigma design the Olympus M.Zuiko 75mm F1.8? (200 comments in total)

Joseph S Wisniewski: Makes a lot of sense to me. The thing I don't get is why Oly?

75mm is a bit of an odd duck on four thirds, 3.5x the "normal" focal length for four thirds (a 150mm equivalent). The classic portrait lenses are 85, 105, and 135mm, 2x, 2.5x, and 3x normal.

75mm is the portrait lens that everyone wants on APS-C, where it's 2.5x normal, but quite awkward on four thirds.

I thought the reason was that Oly wanted to provide a portrait lens with similar ability to throw areas out of focus to a more normal portrait length lens on APS-C cameras.
