This is a 1956 LEICA Elmar lens serial number 1382234 is in outstanding condition. Lens functions fine upon testing with beautifuloptics. I find no fog, haze, or mold in the lens. With that said however, I am not a camera expert. I do not inspect under a microscope which provides a full transparency. I use high light and a loop to inspect lenses. I recommend a full service on all high-quality LEICA cameras and lenses for optimum function and performance. This is an antique camera lens and comes as found. Not happy with the lens? No problem! I provide free returns and will refund your purchase price upon processing the return. Please, no post-transaction haggling. If you are truly unsatisfied with your purchase, open a return. No partial refunds. Comes with front and rear cap.
