There are a couple of negligible specs of dust on optics. 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. This LEICA SUMMITAR 50mm f/2 was Leica's highest-performance normal lens from 1939 until it was replaced by the SUMMICRON in 1953. This SUMMITAR replaced the earlier SUMMAR 50mm f/2.This SUMMITAR was in turn repalced by the improved SUMMICRON. This SUMMITAR uses much larger front optical components than the SUMMAR for greatly reduced mechanical vignetting for less light falloff.
LEICA pitched this as especially important for the new color work for which this SUMMITAR was particularly well suited. Additionally, the new front optical component of this SUMMITAR is now two cemented elements, replacing the single front element of the older SUMMAR.This LEICA SUMMITAR 50mm f/2 works perfectly on every LEICA M camera, from the LEICA M3. Of 1954, today's LEICA M7. LEICA MP and LEICA M9. So long as you use a simple screw-mount adapter. Without the adapter, this SUMMITAR works flawlessly on all traditional (screw-mount) LEICAs, like the popular LEICA IIIf. These screw-mount lenses are thus perfectly compatible with all LEICAs made since 1932.
