I am selling an adapter to convert an R mount to an M mount, along with a Leica APO Macro Elmarit lens. If you have an M-type camera, you can start shooting immediately. Adapter R mount M 14642 APO-Macro-Elmarit-R 100mm F2.8 E60 ROM specification The stunning image quality is still present even with high-resolution digital cameras. It is fully compatible with the M11. I am selling this because I rarely use it and would like to use the funds for future photography. Stored in a dehumidified storage. The lens is very clear. There are no scratches or mold. However, if you shine an LED light on it, you can see what looks like dust or particles. This is the same even with new Leica lenses. Please understand this. Overall, there are no noticeable scratches. When in macro mode, the overall length increases, and I found a scratch on the lens barrel that is usually hidden, so I have included a photo. I took the photo to be quite noticeable, but it is almost unnoticeable to the naked eye. I swear. Included accessories: genuine protective filter, genuine front cap. The rear cap is included, but I'm not sure if it's genuine. Please check the first photo. The serial number starts with 374 and has 7 digits. There are no noticeable scratches on the mount. The aperture blades are clean. The click feel is very good. I selected the X mount when listing, but it is a Leica R mount. I think both are in near-mint condition, but please understand that they are used and purchase accordingly. No returns, no refunds. Please refrain from price negotiations.
