I have a friend who has a Type 109, he commented the build is better than LX100. Some have said, dunno true or not, Leica rebadged Panny has different lens coating as well.
Yeap to both, hence I guess why quite a few willing to spend the extra this time round.
One big question I need to find an answer to is that while on the whole the Raws are supposed to be the same but sensor hardware can be the same but they may be tweaked differently according to manufacturer and was this tweaked also.
