I have used this lens for about 5 years and have not had any issues. For its age the lens from my observation is clean and clear. I have used it on film and digital Leicas and the image rendering is good. There is some marks on the body of the lens so please view images carefully.
The glass has some cleaning marks from over the years but I personally haven't noticed anything out of the ordinary in photos. I have placed a rubber O-ring behind the front of the lens.
Aperture blades are clean and clear of oil. Please view sample photos taken with lens on a Leica M240.Front and rear lens caps included. Lens only, Camera body in images NOT included. Please feel free to message me any questions.
