I have decided to sell my Leica Summicron-C 40 f/2 lens instead of my Summicron 35. Overall excellent+ condition showing very little wear. Aperture clicks and stops smoothly without excessive wear or oil on the blades. Optically near perfect with very little dust and free from scratches or blemishes. Focus is smooth and well-dampened. A great little lens to work with your Leica CL or Leica-M bodies...I have used this and others with great results on M bodies and find the 40 a perfect focal length when you don't want to carry a 35 and a 50! Compact, fast and sharp as a tack.
