Mamiya Sekor C 80mm f/1.9 - Mamiya M645 Mount

The Sekor C 80mm f/1.9 holds the distinction of being the fastest lens produced for a medium format system. It provides a standard field of view on M645 bodies with a very shallow depth of field, making it highly desirable for portrait photography. The optical construction uses high-refraction glass to maintain performance at its wide-open setting. Due to the large glass elements and fast aperture, this lens is sensitive to internal haze and fungus; SDS performs a thorough light-box inspection. We check the aperture blades for speed, as oil can cause them to lag at f/1.9. The rubber focus grip should be checked for loosening, and the filter thread for any impact damage that might prevent the use of screw-in filters.
