<p>I have a GX IIIS and want to convert it to a GX III in order to have front lens movements. Can the lens mount from a GX I or II be adapted in place of the holder of a IIIS in order to achieve that goal? I realize that I will not have the full lens communication features of a 'true' IIIS, but I don't care.<br> Thanks for any help or advice<br> Gary Rogers</p>
