Occasional focus hunting with FT lens on EM1: SWD helps?

Robin Wong's testing

Here is a useful review that I had briefly seen and forgotten in a rush of work:


It is consistent with what I have seen - the mFT lenses focus faster but the FT ones can be useful. He does not find the occasional hunting I have found, but I think he did not test much in different lower light conditions. He does say that the SWD ones will focus faster, which makes sense. One lens that seems to focus at least as well on the EM1 is the 50mm f/2 macro - which was slow to focus on FT cameras - but optically outstanding.
