This is a Leica R 28mm Elmarit, one of the best old lenses used in digital cinema. Based on the serial number, it was made in Germany during the peak of the R mount era in the 1980s. Originally an R mount lens, it has been converted to a Nikon F mount, and then further adapted with a Canon EF mount adapter. It has been used in various representative digital cinema/hybrid cameras. It has mainly been used with RED cameras, and occasionally with Arri, Sony, and Blackmagic cameras. It can be used directly or with various adapters to fit most cameras. It was useful for utilizing the image quality and characteristics without the budget to rent top-level PL lenses from equipment rental companies for tens of thousands of yen per day. It can be used directly or with various adapters to fit most cameras. It has a 77mm front diameter and a focus gear from Duclos, allowing for smooth follow focus operation. The condition is as shown in the photos. Although there is some dust and debris, it is optically near perfect. I think it's in very good condition. It works well as is. It can be further upgraded with products from Simmod, etc. Or, you can spend nearly 1 million yen to rehouse it with ZeroOptik, TLS, or GL Optics. As this is a used item, no claims or returns are accepted for any reason. #leica #cinema #arri #sony #red #smalhd #zeiss #vintagelens #oldlens The original 49mm lens cap and a clear filter are also included. - Focal Length: 28mm - Maximum Aperture: f/2.8 - Filter Diameter: 77mm - Country of Manufacture: Germany Other features...
