I have heard numerous times that Leica has moved beyond the pressed blank
technology to another one having to do with a lot of laser computer
grinding. That kind of thing I think.
That's ok with me I find the idea of my outer elements shipped in hot soft
and fresh from Hoya unnerving.
Anyone know about this?
Maybe I dreamed it.
