I was just wondering... will the newer Pany 14-42mm lens work on the GF1? Since this new lens no longer has an external O.I.S. on/off switch, this function is now controlled through the camera's menu system (such as that of the GH2 and GF2). But what happens if I attach this lens to an older camera such as the GF1? Will the camera automatically adapt and add that function into its menu? I hope you guys can enlighten me on this. TIA!
