Vintage Carl Zeiss Jena Flektogon MC 50mm f/4 wide-angle lens, manufactured in the former German Democratic Republic (DDR). Designed for medium format cameras with the Pentacon Six mount, this classic German lens is highly regarded for its optical performance and wide-angle perspective.

The Flektogon 50mm f/4 was one of the widest-angle lenses available for the Pentacon Six medium format camera system. It is suitable for landscape, architecture, interior photography, and other applications where a wide field of view is desirable.

The MC (multi-coated) version features improved optical coating to help reduce reflections and improve image contrast.
