    75–200mm · f/4.5

    Overview

    The Porst Tele-Zoom 75-200 mm f/4.5 is a vintage manual-focus lens with a constant aperture. Optically, it offers decent sharpness in the center but softens at the edges, especially at the long end, and shows some chromatic aberration. Build quality is typical of its era: all-metal construction with a smooth zoom and focus ring, though it is heavy. It handles well on a tripod but can be front-heavy on smaller cameras. This lens suits photographers interested in retro character and manual operation, but not those seeking modern optical perfection.
