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 
&ldquo;MultiFunction&rdquo; 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)*
