Leica MACRO-ELMAR-R 100mm F4 3CAM Macro Elmar R 3-cam R mount Used with Leica SLR cameras. This is not a Leica M mount. Since it's a 3-cam lens, it can be used with Leica SLR cameras from the R4 onwards. I've actually used it with an R8. Accessories include the genuine lens caps in the images (both front and mount are included). [Lens Features] This macro lens for Leica R, which was originally a close-up lens for bellows with outstanding descriptive performance, was introduced in 1968 in response to the long-standing requests of Leica R series enthusiasts. It incorporates a focusing mechanism. The lens name and serial number are engraved on the front of the filter ring. It has a built-in floating mechanism and is highly regarded for its excellent depiction from close-up to infinity. Including the built-in hood, it has a solid construction, giving a sense of German industrial craftsmanship. This lens received a rating of 4 out of 5 in Leica lens evaluations, with the merit being "extremely stable depiction" and the demerit being "none in particular." [Optics] There is a small amount of dust when light shines through. This does not affect the photography. There is no balsam separation. There are no wiping scratches on the lens surface. [Appearance] The base coat of the paint is visible on the metal focusing ring (image 3), and there are other areas where the paint has peeled off, but this does not interfere with shooting. Please check the images. Thank you.
