If I were a Canon FF or even APSC user (I was an APSC user once), I would never consider such a slow long lens. For wildlife, shooting under the sun doesn't result in the most flattering images, I like shooting in overcast days to avoid the contrasty shadows. For sports, the shutter speed would be too slow. This would make these lenses pointless to me. Why they didn't go with f/8 is beyond me. Still slow, but with the DO optics, they still can be reasonably small.

These do the same job as f/5.6 lenses on mFT. Same diffraction, same DOF and with 2 stops higher ISO also the same noise. Everything is a compromise, here the size, price  and weight are on the plus side, light collecting ability is on the minus side. Worthwhile tradeoff for some people without a doubt.
