About the Leica 50mm f2 Summitar
The LEICA SUMMITAR 50mm f/2 is an extremely sharp lens in the center, and softer on the sides compared to LEICA's newest lenses. In most cases, no one will notice any difference.
The SUMMITAR replaced the earlier SUMMAR 50mm f/2, which was the hot, must-have LEICA lens from 1933-1939. This SUMMITAR was in turn repalced by the improved SUMMICRON in 1952.
This SUMMITAR uses much larger front optical components than the SUMMAR for greatly reduced mechanical vignetting for less light falloff.
Additionally, the new front optical component of this SUMMITAR is now two cemented elements, replacing the single front element of the older SUMMAR.
Without the adapter, this SUMMITAR works flawlessly on all traditional (screw-mount) LEICAs, like the popular LEICA IIIf & IIIg
The SUMMITAR was uncoated prior to World War II, and was coated from about 1946 (about serial nr. 601,001).
The SUMMITAR originally had a 10-bladed diaphragm, which was changed back to the complex 6-bladed design of the previous SUMMAR (1933-1939) in 1950.
7 elements in 4 groups.
Herein lies the secret of the SUMMITAR's performance: most other 50mm f/2 lenses, like Nikon's 5cm f/2 for their contemporary rangefinder cameras, have never used more than 6 elements.
There are no aperture click stops. LEICA didn't invent them until 1953 with the SUMMICRON
