Ernst Abbe Jena B 58mm f2 Lens M42 Mount

The Ernst Abbe Jena B 58mm f/2 is a manual focus standard prime lens produced in East Germany, built for M42 screw mount cameras and associated with the optical manufacturing tradition of the Carl Zeiss Jena facility in Jena, Germany. At 58mm with an f/2 maximum aperture, it delivers a natural field of view well suited to everyday photography, portraiture, and street work, with useful light gathering capability for lower light conditions and meaningful depth of field control for background separation when desired. The B designation refers to a specific optical formula variant within the Jena lens production lineage, and the lens reflects the optical engineering standards associated with the Zeiss Jena manufacturing tradition of its era. Fully manual operation covers both focus and aperture adjustment directly on the lens. Compatible with M42 screw mount film SLR bodies, and adaptable to a broad range of mirrorless and other camera systems via standard M42 adapters.
