Well...I'm sure as sure can be..if it is "leica", it is not the "leica" of old. Same goes for "carl zeiss", "kreuznach Schneider" or any of the lens companies partnered with consumer electronics giants. Those lens companies had Lens plants in Germany as well as other places (singapore for example) to produce lenses. I don't think the lenses of these modern consumer cameras would be produced in the same way. It is probably more the design. or specifications...but like anything could be made anywhere by anyone but still be "made" by Leica.
I mean, think about it...what do you actually mean "made by leica"? If panasonic licenses Leica and they own the plant in Indonesia(or whatever) that make them..then YES, they are made by Leica.
Is like anything...there's made in Japan Sony, and made in Timbuktu Sony.
