This is the classic 35mm f3.5 Summaron for Leica M mount cameras. It has a 10 blade aperture and a 6 element Symetrical Gauss lens design.
It is in excellent- condition with light to moderate wear and works perfectly. There is a slight ring of haze on an inner element, I can only see it with a flashlight, it does not affect image quality. Otherwise, the lens is clean and scratch free with no fungus nor other issues. The focus and aperture are smooth.
The plastic lens bubble is included.
