Elmarit

The name Elmarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.8.

Confusingly not all f/2.8 lenses are Elmarits.

The 50 mm f/2.8 collapsible, manufactured until 2007, was designated an Elmar rather than an Elmarit.

[2] The Elmarit are behind the Summicron and the Summarit lenses.

Only the Elmar and most Summaron lenses have a smaller f-number.
