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 Since then, the Noctilux and Summilux named lenses have superseded this old aperture.[1]

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.[2]

Description

In its current iteration the Summarit lenses have a maximum f-number of f/2.4.[1]

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.[2]
