AF/MF on GF1
MF assist will automatically kick in with a 4/3 lens, even if AF is not supported with that lens.
Obviously, any other legacy lens will not have the electrical connections to tell the body that you're focusing. You can press the command dial to invoke MF assist zoom (with firmware v1.1 or later) or use left arrow + OK to manually trigger zoom.
