African Safari: Panasonic 100-300 or Olympus 75-300?

Thanks for the replies. I think I will give the 100-300 a go and try it out before I go. I'll likely order it soon and I won't be going until the summer so if there is an issue I will have plenty of time to exchange for the Olympus if I then need to.

As long as AFS is good with the E-M5 then I will be happy. Not too concerned with AFC or tracking.

Thanks again.
