    Overview

    The Carl Zeiss Jena Tessar 300mm f/4.5 is a large format lens, often mounted with a custom helicoid (MFlenses). Its optical performance is typical of the Tessar design: good center sharpness but softer corners. Build quality is solid, but handling can be cumbersome due to its size and lack of native focusing. It suits photographers comfortable with adapting vintage large format glass, particularly for portrait or landscape work where central sharpness is prioritized.
