This is one of the best Leica R lenses used in digital cinema. It's a Leica R Macro-Elmarit 60mm, which I've used and loved for cinema. Based on the serial number, it's a German-made lens from the late 1980s, during the peak of the R mount era. Originally an R mount, it has been converted to Nikon F mount, and then further adapted with a Canon EF mount adapter. It has been used with representative digital cinema cameras/hybrid cameras. Mainly RED cameras, and occasionally Arri, Sony, and Blackmagic. It can be used directly or with various adapters to fit most cameras. It was invaluable for utilizing the image quality and character of the lens without the budget to rent top-level PL lenses from equipment rental houses for tens of thousands of yen per day. It can be used directly or with various adapters to fit most cameras. The front diameter is 77mm, and it has a focus gear from Duclos Lenses, allowing for smooth follow focus operation. The condition is as shown in the photos. While there may be some dust and debris, it is optically near perfect. I believe it's in very good condition. It works well as is. It can be further upgraded with products from Simmod, etc. Or, you could spend nearly a million yen to rehouse it with ZeroOptik, TLS, or GL Optics. As this is a used item, no claims or returns will be accepted for any reason. #leica #cinema #arri #sony #red #smalhd #zeiss #vintagelens #oldlens Size...Canon EF mount Focal Length...60mm Maximum Aperture...2.8 Other Features...Old lens, with rear lens cap, with front lens cap
