Martin, the EM-1 also works as you explain, except the rear dial changes the X
and the camera defaults to mode2. I use the fn2 for magnify & the preview
button for peaking. With a m4/3 lens, you only have 2 sec to touch the focus
ring and turn the rear dial. If there is another way, I haven't found it.

Chuck:In order for the IBIS to work in magnified view with MF lenses you need
to do the following (mine is set up this way, I checked):
enable manual magnified view function
* allocate Fn2 button to magnified view * by default this is already set to
“MultiFunction” and thus by holding it down you can set it to
Magnified View functionality, alternatively, set the button to Magnify via the
menu system as for other buttons. * the default behaviour is that when you
touch the shutter button to activate IS as above, you are automatically exited
from magnified view mode - exactly what we don't want. o to enable concurrent
activation of IS and legacy lens magnified view, we need to set one more menu
item: + *set LV Close Up Mode to mode 2 (this is under Custom Menu, Disp/PC)*
