Summarit
Leica Camera lenses

The name Summarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.4. The name has been in use since 1949.
History
The Summarit was initially introduced as Leica's fastest lens in 1949 with a maximum aperture of f/1.5. Since then, the Noctilux and Summilux named lenses have superseded this old aperture.
On 3 August 2007 Leica revived the name and announced a series of less expensive lenses, the Summarit-M. The Summarit-M lenses work on Leica M-series film and digital rangefinder cameras.
Description
In its current iteration the Summarit lenses have a maximum f-number of f/2.4.
Market positions
Leica introduced these less expensive lenses, which also fit Leica M mount cameras like the recent Cosina (Carl Zeiss AG and Voigtländer brands) lenses as an alternative to its main line professional and expensive lenses.
This brief starts where responsible research should: with the source description of “Summarit” as leica Camera lenses. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as leica Camera lenses. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q76702373. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1949 and 2007.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
