Talk:90mm f/4 Elmar

• Luigi Bertolotti LTM gear is often fascinating by itself: as an example, during the years I put together a small collection of ONE lens : the Elmar 90 f4 : 7 pieces all significantly different each to other:

- "Fat" - "All black" - "All chrome" - "Vulkan and chrome wide front rim" - Ditto, "narrow front rim" - "E-39 filter" - "3-elements"
