The Voigtlander “M” lenses were made for the Leica rangefinder cameras, so they are quite small. In addition to being an alternative lens for Leica M mount, they fit appropriately to the Micro 4/3s cameras with an adapter.
The 75 f/2.8 lens gives us a nice telephoto lens with a small physical size. It is built with all metal construction, and it also comes with an attached (but removable) metal lens hood.
