Greg, welcome back!
Take a look at the thread here on the New 90mm Macro for some views on the
12-100, and I agree with the supporters.
I too was concerned with light gathering of an f/4 lens, but the dual IS of
that lens on the EM1iii will cause you to revise your base assumptions, as
it did mine!
