Micheal mentioned this lens as one I might be interested in for my 35-40 FL range. I've found one, reasonable as he says, but can find no way to use with the G1 without a DIY project to convert to use for 4/3rds. This really isn't my forte'. Is there any other way to use a Hexanon AR lens on the G1 without adding the spacers or grind it down, etc.?
