As sharp a Summicron as they come and priced accordingly. Ring turns butter smoothly and the aperture blades are without any oil. Leica leitz summicron-m 50mm f2 rigid lens-silver chrome red scale-yye cla just clad by youxin ye and he did a wonderful job. The front coating has a number of cleaning marks on the front and one slightly deeper scratch as seen, to which I havent noticed any negative affect to image on either digital or film.
