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 Since then, the Noctilux and Summilux named lenses have superseded this old aperture.[1]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

gollark: That's more blueish. Turquoise, maybe.
gollark: The color corrected one looks pretty weird, I guess because it looks like you're not in water.
gollark: I said "[it] seems neat", not "yes I have definitely decided I want to do lots of this and go through a probably somewhat expensive certification/training thing".
gollark: Scuba diving seems neat. I'm doing a "discover scuba diving" thing next month (not sure exactly when, since I had my parents book it and forgot to ask...).
gollark: It looks low enough that mobile networks should still work, although in my experience you're meant to turn off phones for whatever reason.
