This is a Leica Elmar 135mm lens. The exterior has some minor scratches, but the focusing helix is very smooth and I think it's in pretty good condition. As you can see in the photos, there's some minor dust when shining a strong iPhone light through the lens, but it's relatively clean. Elmar 135mm lenses in good condition are hard to find, and many have issues, so I think this one is in relatively good shape. Included accessories are the lens, a Map Camera original simple filter (without any text), and an aftermarket metal rear cap. Thank you. Please refrain from price negotiations. There is no Leica M-mount option, so it's listed as Sony mount.
