Elmar (lens)

The name Elmar is used by Leica to designate camera lenses of four elements.

The Elmar lenses originally had a maximum aperture of f/3.5.

These lenses were derived from a 50 mm f/3.5 Elmax lens first produced in 1925.

[1] The term Elmar is sometimes combined with: Super, Tele, APO, Macro or Vario.

As a result they tend to be smaller and lighter than faster lenses of the same focal length.
